本节主要内容

  1. 操作系统环境准备
  2. Hadoop 2.4.1集群搭建
  3. Spark 1.5.0 集群部署

注:在利用CentOS 6.5操作系统安装spark 1.5集群过程中,本人发现Hadoop 2.4.1集群可以顺利搭建,但在Spark 1.5.0集群启动时出现了问题(可能原因是64位操作系统原因,源码需要重新编译,但本人没经过测试),经本人测试在ubuntu 10.04 操作系统上可以顺利成功搭建。大家可以利用CentOS 6.5进行尝试,如果有问题,再利用ubuntu 10.04搭建,所有步骤基本一致

1. 操作系统环境准备

(1)安装VMWare

  下载地址:http://pan.baidu.com/s/1bniBipD
  密码:pbdw
  安装过程略

(2)下载操作系统并安装

Ubuntu 10.04操作系统下载地址:

链接:http://pan.baidu.com/s/1kTy9Umj 密码:2w5b

CentOS 6.5下载地址:

下载地址:http://pan.baidu.com/s/1mgkuKdi
密码:xtm5

本实验要求装三台:CentOS 6.5,可以分别安装,也可以安装完一台后克隆两台,具体过程略。初学者,建议三台分别安装。安装后如下图所示:
这里写图片描述

(3)CentOS 6.5网络配置

安装好的虚拟机一般默认使用的是NAT(关于NAT、桥接等虚拟机网络连接方式参见本人博客:http://blog.csdn.net/lovehuangjiaju/article/details/48183485),由于三台机器之间需要互通之外,还需要与本机连通,因此采用将网络连接方式设置为Bridged(三台机器相同的设置),如下图所法:
这里写图片描述

修改主机名

(1)修改centos_salve01虚拟机主机名:

vim /etc/sysconfig/network

/etc/sysconfig/network修改后的内容如下:
这里写图片描述

(2)vim /etc/sysconfig/network命令修改centos_slave02虚拟机主机名
/etc/sysconfig/network修改后的内容如下:
这里写图片描述

(3)vim /etc/sysconfig/network命令修改centos_slave03虚拟机主机名
/etc/sysconfig/network修改后的内容如下:
这里写图片描述

修改主机IP地址

在大家在配置时,修改/etc/sysconfig/network-scripts/ifcfg-eth0文件对应的BOOTPROT=static、IPADDR、NETMASK、GATEWAY及DNS1信息即可

(1)修改centos_salve01虚拟机主机IP地址:

vim /etc/sysconfig/network-scripts/ifcfg-eth0

修改后内容如下:

DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0c:29:3f:69:4d"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="5315276c-db0d-4061-9c76-9ea86ba9758e"
IPADDR="192.168.1.111"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.1"
DNS1="8.8.8.8"

这里写图片描述
(2)修改centos_salve02虚拟机主机IP地址:

vim /etc/sysconfig/network-scripts/ifcfg-eth0

修改后内容如下:

DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0c:29:64:f9:80"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="5315276c-db0d-4061-9c76-9ea86ba9758e"
IPADDR="192.168.1.112"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.1"
DNS1="8.8.8.8"

这里写图片描述

(3)修改centos_salve03虚拟机主机IP地址:

vim /etc/sysconfig/network-scripts/ifcfg-eth0

修改后内容如下:

DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0c:29:1e:80:b1"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="5315276c-db0d-4061-9c76-9ea86ba9758e"
IPADDR="192.168.1.113"
NETMASK="255.255.255.0"
GATEWAY="192.168.1.1"
DNS1="8.8.8.8"

这里写图片描述

/etc/sysconfig/network-scripts/ifcfg-eth0文件内容解析:

DEVICE=eth0                 //指出设备名称
BOOTPROT=static             //启动类型 dhcp|static,使用桥接模式,必须是static
HWADDR=00:06:5B:FE:DF:7C    //硬件Mac地址
IPADDR=192.168.0.2          //IP地址
NETMASK=255.255.255.0       //子网掩码
NETWORK=192.168.0.0         //网络地址
GATEWAY=192.168.0.1         //网关地址
ONBOOT=yes                  //是否启动应用
TYPE=Ethernet               //网络类型

设置完成后,使用

service network restart

命令重新启动网络,配置即可生效。

设置主机名与IP地址映射

(1)修改centos_salve01主机名与IP地址映射

vim /etc/hosts

设置内容如下:

127.0.0.1 slave01.example.com  localhost localhost.localdomain localhost4 localhost4.localdomain4
::1       slave01.example.com
192.168.1.111 slave01.example.com
192.168.1.112 slave02.example.com
192.168.1.113 slave03.example.com
具体如下图:

这里写图片描述

(2)修改centos_salve02主机名与IP地址映射

vim /etc/hosts

设置内容如下:

127.0.0.1 slave02.example.com  localhost localhost.localdomain localhost4 localhost4.localdomain4
::1       slave02.example.com
192.168.1.111 slave01.example.com
192.168.1.112 slave02.example.com
192.168.1.113 slave03.example.com

具体如下图:
这里写图片描述

(3)修改centos_salve03主机名与IP地址映射

vim /etc/hosts

设置内容如下:

127.0.0.1 slave03.example.com  localhost localhost.localdomain localhost4 localhost4.localdomain4
::1       slave03.example.com
192.168.1.111 slave01.example.com
192.168.1.112 slave02.example.com
192.168.1.113 slave03.example.com

这里写图片描述

修改主机DNS

采用下列命令设置各主机DNS(三台机器进行相同的设置)

vim /etc/resolv.conf 

设置后的内容:

# Generated by NetworkManager
search example.com
nameserver 8.8.8.8

8.8.8.8为Google提供的DNS服务器

网络连通测试

前面所有的配置完成后,重启centos_salve01、centos_salve02、centos_salve03使主机名设置生效,然后分别在三台机器上作如下测试命令:
下面只给出在centos_salve01虚拟机上的测试

[root@slave01 ~]# ping slave02.example.com
PING slave02.example.com (192.168.1.112) 56(84) bytes of data.
64 bytes from slave02.example.com (192.168.1.112): icmp_seq=1 ttl=64 time=0.417 ms

2 packets transmitted, 2 received, 0% packet loss, time 1799ms
rtt min/avg/max/mdev = 0.281/0.333/0.386/0.055 ms

测试外网的连通性(我在装的时候,8.8.8.8,已经被禁用….心中一万头cnm):

[root@slave01 ~]# ping www.baidu.com
ping: unknown host www.baidu.com
[root@slave01 ~]# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
From 192.168.1.111 icmp_seq=2 Destination Host Unreachable
From 192.168.1.111 icmp_seq=3 Destination Host Unreachable
From 192.168.1.111 icmp_seq=4 Destination Host Unreachable
From 192.168.1.111 icmp_seq=6 Destination Host Unreachable
From 192.168.1.111 icmp_seq=7 Destination Host Unreachable
From 192.168.1.111 icmp_seq=8 Destination Host Unreachable

(4)SSH完密码登录

#### (1) OpenSSH安装
如果大家在配置时,ping 8.8.8.8能够ping通,则主机能够正常上网;如果不能上网,则将网络连接方式重新设置为NAT,并修改网络配置文件为dhcp方式。在保证网络连通的情况下执行下列命令:

yum install openssh-server

#### (2) 无密码登录实现

使用以下命令生成相应的密钥(三台机器进行相同的操作)

ssh-keygen -t rsa 

执行过程一直回车即可

[root@slave01 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
4e:2f:39:ed:f4:32:2e:a3:55:62:f5:8a:0d:c5:2c:16 root@slave01.example.com
The key's randomart image is:
+--[ RSA 2048]----+
|        E        |
|         +       |
|        o =      |
|       . + .     |
|        S . .    |
|       + X .     |
|        B *      |
|       .o=o.     |
|      .. +oo.    |
+-----------------+

生成的文件分别为/root/.ssh/id_rsa(私钥)、/root/.ssh/id_rsa.pub(公钥)

完成后将公钥拷贝到要免登陆的机器上(三台可进行相同操作):

ssh-copy-id -i slave01.example.com
ssh-copy-id -i slave02.example.com
ssh-copy-id -i slave03.example.com

2. Hadoop 2.4.1集群搭建

集群搭建相关软件下载地址:

链接:http://pan.baidu.com/s/1sjIG3b3 密码:38gh

下载后将所有软件都放置在E盘的share目录下:
这里写图片描述

设置share文件夹为虚拟机的共享目录,如下图所示:
这里写图片描述

在linux系统中,采用

[root@slave01 /]# cd /mnt/hgfs/share
[root@slave01 share]# ls

命令可以切换到该目录下,如下图
这里写图片描述

Spark官方要求的JDK、Scala版本

Spark runs on Java 7+, Python 2.6+ and R 3.1+. For the Scala API, Spark 1.5.0 uses Scala 2.10. You will need to use a compatible Scala version (2.10.x).

(1)JDK 1.8 安装

在根目录下创建sparkLearning目前,后续所有相关软件都放置在该目录下,代码如下:

[root@slave01 /]# mkdir /sparkLearning
[root@slave01 /]# ls
bin   etc             lib         media  proc  selinux        sys  var
boot  hadoopLearning  lib64       mnt    root  sparkLearning  tmp
dev   home            lost+found  opt    sbin  srv            usr

将共享目录中的jdk安装包复制到/sparkLearning目录

[root@slave01 share]# cp /mnt/hgfs/share/jdk-8u40-linux-x64.gz /sparkLearning/
[root@slave01 share]# cd /sparkLearning/
//解压
[root@slave01 sparkLearning]# tar -zxvf jdk-8u40-linux-x64.gz 

设置环境变量:

[root@slave01 sparkLearning]# vim /etc/profile

在文件最后添加:

export JAVA_HOME=/sparkLearning/jdk1.8.0_40
export PATH=${JAVA_HOME}/bin:$PATH

如下图:
这里写图片描述

测试配置是否成功:

//使修改后的配置生效
[root@slave01 sparkLearning]# source /etc/profile
//环境变量是否已经设置
[root@slave01 sparkLearning]# $JAVA_HOME
bash: /sparkLearning/jdk1.8.0_40: is a directory
//测试java是否安装配置成功
[root@slave01 sparkLearning]# java -version
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b25)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

(2)Scala 2.10.4 安装

//复制文件到sparkLearning目录下
[root@slave01 sparkLearning]# cp /mnt/hgfs/share/scala-2.10.4.tgz  .
//解压
[root@slave01 sparkLearning]# tar -zxvf scala-2.10.4.tgz > /dev/null


[root@slave01 sparkLearning]# vim /etc/profile

将/etc/profile文件末尾内容修改如下:

export JAVA_HOME=/sparkLearning/jdk1.8.0_40
export SCALA_HOME=/sparkLearning/scala-2.10.4
export PATH=${JAVA_HOME}/bin:${SCALA_HOME}/bin:$PATH

测试Scala是否安装成功

[root@slave01 sparkLearning]# source /etc/profile
[root@slave01 sparkLearning]# $SCALA_HOME
bash: /sparkLearning/scala-2.10.4: is a directory
[root@slave01 sparkLearning]# scala -version
Scala code runner version 2.10.4 -- Copyright 2002-2013, LAMP/EPFL

(3)Zookeeper-3.4.5 集群搭建

[root@slave01 sparkLearning]# cp /mnt/hgfs/share/zookeeper-3.4.5.tar.gz .
[root@slave01 sparkLearning]# tar -zxvf zookeeper-3.4.5.tar.gz > /dev/null

[root@slave01 sparkLearning]# cp zookeeper-3.4.5/conf/zoo_sample.cfg zoo.cfg
[root@slave01 sparkLearning]# vim zoo.cfg

修改dataDir为:

dataDir=/sparkLearning/zookeeper-3.4.5/zookeeper_data

在文件末尾添加如下内容:

server.1=slave01.example.com:2888:3888
server.2=slave02.example.com:2888:3888
server.3=slave03.example.com:2888:3888

如图所示:
这里写图片描述

这里写图片描述

创建ZooKeeper集群数据保存目录

[root@slave01 sparkLearning]# cd zookeeper-3.4.5/
[root@slave01 zookeeper-3.4.5]# mkdir zookeeper_data
[root@slave01 zookeeper-3.4.5]# cd zookeeper_data/
[root@slave01 zookeeper_data]# touch myid 
[root@slave01 zookeeper_data]# echo 1 > myid 

将slave01.example.com(centos_slave01)上的sparkLearning目录拷贝到另外两台服务器上:

[root@slave01 /]# scp -r /sparkLearning slave02.example.com:/
[root@slave01 /]# scp -r /sparkLearning slave03.example.com:/

/etc/profile文件也进行覆盖

[root@slave01 /]# scp  /etc/profile slave02.example.com:/etc/profile
[root@slave01 /]# scp  /etc/profile slave03.example.com:/etc/profile

修改zookeeper_data中的myid信息:

//配置slave02.example.com上的myid
[root@slave01 /]# ssh salve02.example.com
[root@slave02 ~]# echo 2 > /sparkLearning/zookeeper-3.4.5/zookeeper_data/myid
[root@slave02 ~]# more /sparkLearning/zookeeper-3.4.5/zookeeper_data/myid
2
//配置slave03.example.com上的myid
[root@slave02 ~]# ssh slave03.example.com
Last login: Fri Sep 18 01:33:29 2015 from slave01.example.com
[root@slave03 ~]# echo 3 > /sparkLearning/zookeeper-3.4.5/zookeeper_data/myid
[root@slave03 ~]# more /sparkLearning/zookeeper-3.4.5/zookeeper_data/myid
3

如此便完成配置,下面对集群进行测试:

//在slave03.example.com主机上
[root@slave03 ~]# cd /sparkLearning/zookeeper-3.4.5/bin
[root@slave03 bin]# ls
README.txt    zkCli.cmd  zkEnv.cmd  zkServer.cmd
zkCleanup.sh  zkCli.sh   zkEnv.sh   zkServer.sh

//启动slave03.example.com上的ZooKeeper
[root@slave03 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /sparkLearning/zookeeper-3.4.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@slave03 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /sparkLearning/zookeeper-3.4.5/bin/../conf/zoo.cfg
Mode: leader

//在slave02.example.com主机上
[root@slave02 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /sparkLearning/zookeeper-3.4.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
//查看zookeeper集群状态,如果Mode显示为follower或leader则表明配置成功
[root@slave02 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /sparkLearning/zookeeper-3.4.5/bin/../conf/zoo.cfg
Mode: follower


//在slave01.example.com主机上
[root@slave01 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /sparkLearning/zookeeper-3.4.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@slave01 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /sparkLearning/zookeeper-3.4.5/bin/../conf/zoo.cfg
Mode: follower

//在slave03.example.com主机上zookeeper状态
[root@slave03 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /sparkLearning/zookeeper-3.4.5/bin/../conf/zoo.cfg
Mode: leader

(4)Hadoop 2.4.1 集群搭建

(1)Hadoop 2.4.1基本目录浏览

root@slave01 bin]# cp /mnt/hgfs/share/hadoop-2.4.1.tar.gz /sparkLearning/
[root@slave01 bin]# cd /sparkLearning/
[root@slave01 sparkLearning]# tar -zxvf hadoop-2.4.1.tar.gz > /dev/null
[root@slave01 sparkLearning]# cd hadoop-2.4.1
[root@slave01 hadoop-2.4.1]# ls
bin  include  libexec      NOTICE.txt  sbin
etc  lib      LICENSE.txt  README.txt  share
cd 
[root@slave01 hadoop-2.4.1]# cd etc/hadoop/
[root@slave01 hadoop]# ls
capacity-scheduler.xml      hdfs-site.xml               mapred-site.xml.template
configuration.xsl           httpfs-env.sh               slaves
container-executor.cfg      httpfs-log4j.properties     ssl-client.xml.example
core-site.xml               httpfs-signature.secret     ssl-server.xml.example
hadoop-env.cmd              httpfs-site.xml             yarn-env.cmd
hadoop-env.sh               log4j.properties            yarn-env.sh
hadoop-metrics2.properties  mapred-env.cmd              yarn-site.xml
hadoop-metrics.properties   mapred-env.sh
hadoop-policy.xml           mapred-queues.xml.template

(2)将Hadoop 2.4.1添加到环境变量

使用命令:vim /etc/profile 将环境变量信息修改如下:

export JAVA_HOME=/sparkLearning/jdk1.8.0_40
export SCALA_HOME=/sparkLearning/scala-2.10.4
export HADOOP_HOME=/sparkLearning/hadoop-2.4.1
export PATH=${JAVA_HOME}/bin:${SCALA_HOME}/bin:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin:$PATH

(3)将Hadoop 2.4.1添加到环境变量

使用命令:vim hadoop-env.sh 将环境变量信息修改如下,在export JAVA_HOME修改为:

export JAVA_HOME=/sparkLearning/jdk1.8.0_40

这里写图片描述

(4)修改core-site.xml文件

利用vim core-site.xml命令,文件内容如下:

  <configuration>
<!-- 指定hdfs的nameservice为ns1 -->
                    <property>
                        <name>fs.defaultFS</name>
                        <value>hdfs://ns1</value>
                    </property>
                    <!-- 指定hadoop临时目录 -->
                    <property>
                        <name>hadoop.tmp.dir</name>
                        <value>/sparkLearning/hadoop-2.4.1/tmp</value>
                    </property>
                    <!-- 指定zookeeper地址 -->
                    <property>
                        <name>ha.zookeeper.quorum</name>
                        <value>slave01.example.com:2181,slave02.example.com:2181,slave03.example.com:2181</value>
                    </property>
</configuration>

(5)修改hdfs-site.xml文件

vim hdfs-site.xml内容如下:

<configuration>
                <!--指定hdfs的nameservice为ns1,需要和core-site.xml中的保持一致 -->
                <property>
                    <name>dfs.nameservices</name>
                    <value>ns1</value>
                </property>
                <!-- ns1下面有两个NameNode,分别是nn1,nn2 -->
                <property>
                    <name>dfs.ha.namenodes.ns1</name>
                    <value>nn1,nn2</value>
                </property>
                <!-- nn1的RPC通信地址 -->
                <property>
                    <name>dfs.namenode.rpc-address.ns1.nn1</name>
                    <value>slave01.example.com:9000</value>
                </property>
                <!-- nn1的http通信地址 -->
                <property>
                    <name>dfs.namenode.http-address.ns1.nn1</name>
                    <value>slave01.example.com:50070</value>
                </property>
                <!-- nn2的RPC通信地址 -->
                <property>
                    <name>dfs.namenode.rpc-address.ns1.nn2</name>
                    <value>slave02.example.com:9000</value>
                </property>

(15)查看hadoop运行管理界面

打开浏览器,输入http://slave01.example.com:8088/,可以得到hadoop集群管理界面:
这里写图片描述

输入http://slave01.example.com:50070 可以得到HDFS管理界面
这里写图片描述

至此Hadoop集群配置成功

3. Spark 1.5.0 集群部署

(1)将Spark添加到环境变量

[root@slave01 hadoop]# cp /mnt/hgfs/share/spark-1.5.0-bin-hadoop2.4.tgz /sparkLearning/

[root@slave01 sparkLearning]# tar -zxvf spark-1.5.0-bin-hadoop2.4.tgz > /dev/null

[root@slave01 sparkLearning]# vim /etc/profile

将/etc/profile内容修改如下:

export JAVA_HOME=/sparkLearning/jdk1.8.0_40
export SCALA_HOME=/sparkLearning/scala-2.10.4
export HADOOP_HOME=/sparkLearning/hadoop-2.4.1
export SPARK_HOME=/sparkLearning/spark-1.5.0-bin-hadoop2.4
export PATH=${JAVA_HOME}/bin:${SCALA_HOME}/bin:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin:${SPARK_HOME}/bin:${SPARK_HOME}/sbin:$PATH

(2)将Spark添加到环境变量

[root@slave01 sparkLearning]# cd spark-1.5.0-bin-hadoop2.4/conf
[root@slave01 conf]# ls
docker.properties.template  metrics.properties.template   spark-env.sh.template
fairscheduler.xml.template  slaves.template
log4j.properties.template   spark-defaults.conf.template

//复制模板文件
[root@slave01 conf]# cp spark-env.sh.template spark-env.sh
[root@slave01 conf]# vim spark-env.sh

在spark-env.sh文件中添加如下内容:

export JAVA_HOME=/sparkLearning/jdk1.8.0_40
export SCALA_HOME=/sparkLearning/scala-2.10.4
export HADOOP_CONF_DIR=/sparkLearning/hadoop-2.4.1/etc/hadoop
[root@slave01 conf]# cp slaves.template slaves
[root@slave01 conf]# vim slaves

slaves文件内容如下:

# A Spark Worker will be started on each of the machines listed below.
slave01.example.com
slave02.example.com
slave03.example.com

(3)将配置信息复制到其它服务器

[root@slave01 sparkLearning]# scp /etc/profile slave02.example.com:/etc/profile
profile                                       100% 2123     2.1KB/s   00:00    
[root@slave01 sparkLearning]# scp /etc/profile slave03.example.com:/etc/profile
profile                                       100% 2123     2.1KB/s   00:00    
[root@slave01 sparkLearning]# vim /etc/profile
[root@slave01 sparkLearning]# scp -r spark-1.5.0-bin-hadoop2.4 slave02.example.com:/sparkLearning/
...执行过程省略.....
[root@slave01 sparkLearning]# scp -r spark-1.5.0-bin-hadoop2.4 slave03.example.com:/sparkLearning/
...执行过程省略.....

(4)启动Spark集群

因为本人机器上装了Ambari Server,占用了8080端口,而Spark Master默认端是8080,因此将sbin/start-master.sh中的SPARK_MASTER_WEBUI_PORT修改为8888

if [ "$SPARK_MASTER_WEBUI_PORT" = "" ]; then
  SPARK_MASTER_WEBUI_PORT=8888
fi
[root@slave01 sbin]# ./start-all.sh 
starting org.apache.spark.deploy.master.Master, logging to /sparkLearning/spark-1.5.0-bin-hadoop2.4/sbin/../logs/spark-root-org.apache.spark.deploy.master.Master-1-slave01.example.com.out

[root@slave01 sbin]# jps
13744 DataNode
13681 NameNode
14228 NodeManager

11862 QuorumPeerMain
13943 DFSZKFailoverController
14138 ResourceManager
13851 JournalNode
17179 Jps
17087 Worker

浏览器中输入slave01.example.com:8888
这里写图片描述
但是在启动过程中出现了错误,查看日志文件

[root@slave02 logs]# more spark-root-org.apache.spark.deploy.worker.Worker-1-slave02.example.com.out

日志内容中包括下列错误:

akka.actor.ActorNotFound: Actor not found for: ActorSelection[Anchor(akka.tcp://

.....省略.....................

没找到具体原因,在ubuntu 10.04服务器上进行相同的配置,集群搭建却成功了(心中一万头…..),运行界面如下:
这里写图片描述

(5)测试Spark集群

采用下列命上传spark-1.5.0-bin-hadoop2.4目录下的README.md文件到相应的根目录。

 hadoop dfs -put README.md 

如下图:
这里写图片描述

进入/spark-1.5.0-bin-hadoop2.4/bin目录,启动./spark-shell,如下图所示:
这里写图片描述

执行REDME.md文件的wordcount操作:

scala> val textCount = sc.textFile(“README.md”).filter(line => line.contains(“Spark”)).count()

如下图:
这里写图片描述

执行结果如下图:
这里写图片描述

至此,Spark 1.5集群搭建成功。
