HDP Hiveserver2搭建高可用

第一步：添加hiveserver2服务

第二步：增加配置项

第三步：注册

到分别有hiveserver2的机器上面执行命令

[root@hadoop2 ~]# hiveserver2

第四步：验证，一个节点注册

[zk: localhost:2181(CONNECTED) 4] ls /hiveserver2

[serverUri=0.0.0.0:10000;version=1.2.1.2.3.4.0-3485;sequence=0000000005]

第二个节点注册后

[serverUri=hadoop2:10000;version=1.2.1.2.3.4.0-3485;sequence=0000000007, serverUri=0.0.0.0:10000;version=1.2.1.2.3.4.0-3485;sequence=0000000005]

第四步：连接串JDBC连接

JDBC连接的URL格式为：

jdbc:hive2://

其中：

serviceDiscoveryMode=zooKeeper 指定模式为zooKeeper

zooKeeperNamespace=hiveserver2 指定ZK中的nameSpace，即参数hive.server2.zookeeper.namespace所定义，我定义为hiveserver2

第五步：线上使用

beeline> !connect jdbc:hive2://hadoop1:2181,hadoop0:2181,hadoop2:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2;

Connecting to jdbc:hive2://hadoop1:2181,hadoop0:2181,hadoop2:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2;

Enter username for jdbc:hive2://hadoop1:2181,hadoop0:2181,hadoop2:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2;:

Enter password for jdbc:hive2://hadoop1:2181,hadoop0:2181,hadoop2:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2;:

Connected to: Apache Hive (version 1.2.1.2.3.4.0-3485)

Driver: Hive JDBC (version 1.2.1.2.3.4.0-3485)

Transaction isolation: TRANSACTION_REPEATABLE_READ
