[jira] [Commented] (HIVE-25096) beeline can't get the correct hiveserver2 using the zoopkeeper with serviceDiscoveryMode=zooKeeper.
[ https://issues.apache.org/jira/browse/HIVE-25096?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17558155#comment-17558155 ]
Dong Qiu commented on HIVE-25096:
---------------------------------
[~heiheizhang] tested the patch, it fixed the beeline issue. will this be merged ?
another Jira for the same issue. patch in HIVE-19825 should fix that as well.

> You know, HiveServer2#startPrivilegeSynchronizer will create the namespace of /hiveserver2/leader in the zookeeper,
> however, if you want to connect to the hiveserver2 using beeline with the command like "jdbc:hive2://vhost-120-26:2181,vhost-120-27:2181,vhost-120-28:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2", the beeline will randomly chose the sub-namespace under /hiveserver2.
> That arises a problem that the beeline will not find the hiveserver2 information in the namespace of /hiveserver2/leader, it's impossible to detect the hiveserver2 connection information.
>
>
> That's to say, the sub-namespace of /hiveserver2 is like this:
>
> [zk: vhost-120-28:2181,vhost-120-27:2181,vhost-120-26:2181(CONNECTED) 1] ls /hiveserver2
