[jira] [Commented] (HBASE-3612) HBaseAdmin::isTableAvailable( name ) returns true when the table does not exist

["Jean-Daniel Cryans (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-3612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13010978#comment-13010978 ] 

Jean-Daniel Cryans commented on HBASE-3612:
-------------------------------------------

We just found the same issue with HCM.isTableEnabled and I think the fix done in the scope of this jira isn't the right one. If the table doesn't exist, we should throw TableNotFoundException instead of returning _false_.

I propose we reopen this jira, widen it's scope, do the fix that throws the Exception and add some unit tests.

> HBaseAdmin::isTableAvailable( name )  returns true for a table in which HBaseAdmin::tableExists( name ) returns false.
> It appears from the code that the default return value from isTableAvailable() is true and false is only returned in the case where the table is found and not all the region servers are online.
