6.Configure hive-site.xml

点击(此处)折叠或打开

[root@sht-sgmhadoopnn-01 ~]# cd $HIVE_HOME/conf
[root@sht-sgmhadoopnn-01 conf]# cp hive-default.xml.template hive-default.xml
[root@sht-sgmhadoopnn-01 conf]# vi hive-site.xml

7.第一次运行 bin/hive 客户端
[root@sht-sgmhadoopnn-01 hive-2.0.0]# cd bin
[root@sht-sgmhadoopnn-01 bin]# hive
Logging initialized using configuration in jar:file:/hadoop/hive-2.0.0/lib/hive-common-2.0.0.jar!/hive-log4j2.properties
Exception in thread "main" java.lang.RuntimeException: Hive metastore database is not initialized. Please use schematool (e.g. ./schematool -initSchema -dbType ...) to create the schema. If needed, don't forget to include the option to auto-create the underlying database in your JDBC connection string (e.g. ?createDatabaseIfNotExist=true for mysql)

[root@sht-sgmhadoopnn-01 bin]# ll

-rwxr-xr-x 1 root root 884 Apr 23 2015 schematool
You have mail in /var/spool/mail/root

8.初始化 db
[root@sht-sgmhadoopnn-01 bin]# schematool -initSchema -dbType mysql
Metastore connection URL: jdbc:mysql://localhost/hive?createDatabaseIfNotExist=true
Metastore Connection Driver : com.mysql.jdbc.Driver
Metastore connection User: hive
Starting metastore schema initialization to 2.0.0
Initialization script hive-schema-2.0.0.mysql.sql
Initialization script completed
schemaTool completed
You have mail in /var/spool/mail/root
[root@sht-sgmhadoopnn-01 bin]#

9.查看MySQL元数据,show tables
sht-sgmhadoopnn-01.telenav.cn:mysqladmin:/usr/local/mysql:>mysql -uhive -p
mysql> use hive;
Database changed

mysql> show tables;
+---------------------------+
| Tables_in_hive |
+---------------------------+
| aux_table |
| bucketing_cols |
...............
...............
| tbls |
| txn_components |
| txns |
| type_fields |
| types |
| version |
+---------------------------+
55 rows in set (0.00 sec)

10.测试,创建表,插入数据
## "tab制表符"分隔
[root@sht-sgmhadoopnn-01 conf]# vi /tmp/studentInfo.txt
1 a 26 110
2 b 29 120
~

[root@sht-sgmhadoopnn-01 bin]# hive
Logging initialized using configuration in jar:file:/hadoop/hive-2.0.0/lib/hive-common-2.0.0.jar!/hive-log4j2.properties
Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. tez, spark) or using Hive 1.X releases.
hive> create table studentinfo (id int,name string, age int,tel string)
> row format delimited fields terminated by '\t'
> stored as textfile;
OK
Time taken: 2.347 seconds
hive> load data local inpath '/tmp/studentInfo.txt' into table studentinfo;
Loading data to table default.studentinfo
OK
Time taken: 1.383 seconds
hive> select * from studentinfo;
OK
1 a 26 110
2 b 29 120
Time taken: 0.173 seconds, Fetched: 2 row(s)
hive> exit();

11.再次修改两个参数
# "hdfs://mycluster"是指$HADOOP_HOME/etc/hadoop/core-site.xml文件的fs.defaultFS的值(NameNode HA URI)

点击(此处)折叠或打开

[root@sht-sgmhadoopnn-01 conf]# vi hive-site.xml
<property>
<name>hive.metastore.warehouse.dir</name>
<value>hdfs://mycluster/user/hive_local/warehouse</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://sht-sgmhadoopnn-01:3306/hive_local_meta?createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>
</property>

11.再次验证修改的内容，是否成功创建classInfo表
[root@sht-sgmhadoopnn-01 bin]# hive
Logging initialized using configuration in jar:file:/hadoop/hive-2.0.0/lib/hive-common-2.0.0.jar!/hive-log4j2.properties
Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. tez, spark) or using Hive 1.X releases.
hive> create table classInfo(id int,classname string,stucount int) row format delimited fields terminated by '\t'
> stored as textfile;
OK
Time taken: 2.257 seconds
