Hive 4、Hive 的安装配置(远端MyMql模式)
1.remote一体
这种存储方式需要在远端服务器运行一个mysql服务器,并且需要在Hive服务器启动meta服务。这里用mysql的测试服务器,ip位192.168.1.214,新建hive_remote数据库,字符集位latine1;
$ vim hive-site.xml
<configuration> <property> <name>hive.metastore.warehouse.dir</name> <value>/user/hive/warehouse</value> </property> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://192.168.57.6:3306/hive?createDatabaseIfNotExist=true</value> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver</value> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>hive</value> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>password</value> </property> <property> <name>hive.metastore.local</name> <value>false</value> </property> <property> <name>hive.metastore.uris</name> <value>thrift://192.168.1.188:9083</value> </property> </configuration>
注:这里把hive的服务端和客户端都放在同一台服务器上了。服务端和客户端可以拆开
2.Remote分开
将hive-site.xml配置文件拆为如下两部分
1)、服务端配置文件
<configuration> <property> <name>hive.metastore.warehouse.dir</name> <value>/user/hive/warehouse</value> </property> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://192.168.57.6:3306/hive?createDatabaseIfNotExist=true</value> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver</value> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>root</value> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>123456</value> </property> </configuration>
2)、客户端配置文件
<configuration> <property> <name>hive.metastore.warehouse.dir</name> <value>/user/hive/warehouse</value> </property> <property> <name>hive.metastore.local</name> <value>false</value> </property> <property> <name>hive.metastore.uris</name> <value>thrift://192.168.57.5:9083</value> </property> </configuration>
#启动hive服务端程序 $ hive --service metastore #客户端直接使用hive命令即可 $ hive Hive history file=/tmp/root/hive_job_log_root_201301301416_955801255.txt hive> show tables; OK test_hive Time taken: 0.736 seconds hive>
