[jira] [Commented] (HBASE-20020) Make sure we throw DoNotRetryIOException when ConnectionImplementation is closed

    [ https://issues.apache.org/jira/browse/HBASE-20020?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16369823#comment-16369823 ] 

Duo Zhang commented on HBASE-20020:
-----------------------------------

The intention here is that, all related calls to the HBase cluster will finally call these methods in ConnectionImplementation

getClient
locateRegion
getMaster
getTableState
isTableAvailable

So inject closed check for these methods.

Removed the getMasterKeepAliveConnection and make getMaster return MasterKeepAliveConnection directly. Since ClusterConnection is IA.Private we can change it at any time. I'm not familiar with the keep alive logic for master but since MasterKeepAliveConnection is not deprecated so I still make use of it...

Thanks.
