Subject [jira] [Commented] (HBASE-5798) NPE running hbck on 0.94 out of reportTablesInFlux
Date Mon, 16 Apr 2012 18:38:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5798?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13254888#comment-13254888
] 

Jonathan Hsieh commented on HBASE-5798:
---------------------------------------

Returning empty array is valid.  I dug a little into the master side as well -- it returns
an empty array in the case where an invalid set of table names is passed.
