本文主要是介绍Hive安装—远端MySQL模式,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
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
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<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
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<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>
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<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
root@my188:~$ hive
Hive history file=/tmp/root/hive_job_log_root_201301301416_955801255.txt
hive> show tables;
OK
test_hive
