Subject [jira] [Commented] (HBASE-9314) Dropping a table always prints a TableInfoMissingException in the master log
Date Wed, 28 Aug 2013 16:02:52 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13752523#comment-13752523
] 

Jean-Daniel Cryans commented on HBASE-9314:
-------------------------------------------

Yeah that might be ok. It seems this method is only called from the client-side so also printing
it in the master log doesn't add much value.
