Subject [jira] [Commented] (HBASE-11974) When a disabled table is scanned, NotServingRegionException is thrown instead of TableNotEnabledException
Date Thu, 18 Sep 2014 17:30:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11974?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14139210#comment-14139210
] 

Andrey Stepachev commented on HBASE-11974:
------------------------------------------

Hmm, didn't look at 0.98, looking at master.
RpcRetryingCallable#callWithRetries on failure will call prepare(true).
prepare() calls in general will call RpcRetryingCallerWithReadReplicas#getRegionLocations.
Old version used to scan only meta region for new region location. But patched version will
scan meta _and_ issue isTableDisable RPC. That what about I asked, is it desirable to have
an additional call?
