Subject [jira] [Commented] (HBASE-11490) In HBase Shell set_peer_tableCFs, if the tableCFS is null, it will be wrong
Date Fri, 21 Aug 2015 04:42:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11490?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14706226#comment-14706226
] 

Anoop Sam John commented on HBASE-11490:
----------------------------------------

patch looks ok.
nit : 
tableCFs = new byte[0];
Instead use HConstants.EMPTY_BYTE_ARRAY.

Will be better to add an FT test case as Ashish suggested.
