简介： 1.已有环境:Hadoop-2.7.2+zookeeper-3.4.6完全分布式环境搭建(HDFS、YARN HA) 2.下载解压hbase-1.2.0-bin.tar.

1.已有环境: Hadoop-2.7.2+zookeeper-3.4.6完全分布式环境搭建(HDFS、YARN HA)

2. 下载解压hbase-1.2.0-bin.tar.gz和设置环境HBASE_HOME变量

[root@sht-sgmhadoopnn-01 tmp]# wget http://archive.apache.org/dist/hbase/1.1.5/hbase-1.1.5-bin.tar.gz
[root@sht-sgmhadoopnn-01 tmp]# tar -xvf hbase-1.1.5-bin.tar.gz
[root@sht-sgmhadoopnn-01 tmp]# mv /tmp/hbase-1.1.5 /hadoop/hbase
[root@sht-sgmhadoopnn-01 tmp]# cd /hadoop/hbase/conf
[root@sht-sgmhadoopnn-01 conf]# pwd
/hadoop/hbase/conf

vi /etc/profile 增加内容如下:[集群所有节点设置]

点击(此处)折叠或打开

export HBASE_HOME=/hadoop/hbase
PATH=.:$HADOOP_HOME/bin:$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin:HBASE_HOME/bin:$PATH
export $PATH

执行 source /etc/profile

3. 修改hbase-env.sh

export JAVA_HOME="/usr/java/jdk1.7.0_67-cloudera"

export HBASE_CLASSPATH=/hadoop/hadoop-2.7.2/etc/hadoop

#设置到Hadoop的etc/hadoop目录是用来引导Hbase找到Hadoop,也就是说hbase和hadoop进行关联【必须设置,否则hmaster起不来】

export HBASE_MANAGES_ZK=false

#不启用hbase自带的zookeeper
4.修改hbase-site.xml

点击(此处)折叠或打开

<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://mycluster/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>/hadoop/hbase/tmp</value>
</property>
<property>
<name>hbase.master</name>
<value>60000</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/hadoop/zookeeper/data</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>sht-sgmhadoopdn-01,sht-sgmhadoopdn-02,sht-sgmhadoopdn-03</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
<property>
<name>zookeeper.session.timeout</name>
<value>120000</value>
</property>
<property>
<name>hbase.regionserver.restart.on.zk.expire</name>
<value>true</value>
</property>
</configuration>

5. 修改regionservers文件

点击(此处)折叠或打开

sht-sgmhadoopdn-01
sht-sgmhadoopdn-02
sht-sgmhadoopdn-03

6.分发文件夹

点击(此处)折叠或打开

[root@sht-sgmhadoopnn-01 hadoop]# scp -r hbase root@sht-sgmhadoopnn-02:/hadoop
[root@sht-sgmhadoopnn-01 hadoop]# scp -r hbase root@sht-sgmhadoopdn-01:/hadoop
[root@sht-sgmhadoopnn-01 hadoop]# scp -r hbase root@sht-sgmhadoopdn-02:/hadoop
[root@sht-sgmhadoopnn-01 hadoop]# scp -r hbase root@sht-sgmhadoopdn-03:/hadoop

7.启动HBase HA

点击(此处)折叠或打开

[root@sht-sgmhadoopnn-01 bin]# start-hbase.sh
[root@sht-sgmhadoopnn-02 bin]# hbase-daemon.sh start master

8.验证 是否已经启动hbase集群和验证who is master and who is Backup Master
1).进程和查询服务器状态

点击(此处)折叠或打开

##进程 [root@sht-sgmhadoopnn-01 bin]# jps
20519 NameNode
18925 Jps
20872 DFSZKFailoverController
26810 ResourceManager
13564 HMaster

[root@sht-sgmhadoopnn-02 logs]# jps
5265 NameNode
5449 DFSZKFailoverController
26319 Jps
12281 ResourceManager
21879 HMaster
[root@sht-sgmhadoopdn-01 bin]# jps
30488 QuorumPeerMain
25780 NodeManager
20286 DataNode
996 HRegionServer
6371 Jps
20399 JournalNode
### sht-sgmhadoopdn-02,03与01一样

##查询服务器状态 [root@sht-sgmhadoopnn-01 bin]# hbase shell 2016-03-16 22:55:36,551 WARN [main] util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
HBase Shell; enter 'help' for list of supported commands.
Type "exit" to leave the HBase Shell
Version 1.2.0, r25b281972df2f5b15c426c8963cbf77dd853a5ad, Thu Feb 18 23:01:49 CST 2016

hbase(main):001:0> status 1 active master, 1 backup masters, 3 servers, 0 dead, 0.6667 average load

2).查看日志

3).登录zookeeper

4).web 页面

why http://server:60010 web page for the running HBase1.1.5 Master???

After the 0.98 version port numbers have changed. It is now 16010 instead of 60010). Check this page for general UI troubleshooting: http://hbase.apache.org/book/trouble.tools.html
