Subject [jira] [Commented] (HBASE-11974) When a disabled table is scanned, NotServingRegionException is thrown instead of TableNotEnabledException
Date Thu, 18 Sep 2014 17:38:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11974?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14139226#comment-14139226

Ted Yu commented on HBASE-11974:
--------------------------------

Throwing NotServingRegionException to client for disabled table is a regression.
NotServingRegionException doesn't extend DoNotRetryIOException. So client would likely retry,
without the fix.
At some point, client may issue isTableDisable call and stop retrying.

The proposed fix doesn't add extra RPC compared with 0.98

> When a disabled table is scanned, TableNotEnabledException should be thrown.
> However, currently NotServingRegionException is thrown.
