Subject [jira] [Commented] (HBASE-3052) Add ability to have multiple ZK servers in a quorum in MiniZooKeeperCluster for test writing
Date Mon, 21 Mar 2011 23:03:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3052?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009460#comment-13009460

Liyin Tang commented on HBASE-3052:
-----------------------------------

Yes, the candiate is ambiguous,I should change to backupZooKeeperServers.
right now, there is only one active ZK running.
It sounds like I need to make all of ZK servers running together at beginning 
and the client can kill anyone of them. 

Is it true that there is still only one of ZK server is active ?

Thanks

> Interesting things can happen when you have a ZK quorum of multiple servers and one of
them dies.  Doing testing here on clusters, this has turned up some bugs with HBase interaction
with ZK.
> Would be good to add the ability to have multiple ZK servers in unit tests and be able
to kill them individually.
