Subject [jira] [Commented] (HBASE-5424) HTable meet NPE when call getRegionInfo()
Date Fri, 17 Feb 2012 17:56:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13210417#comment-13210417

stack commented on HBASE-5424:

Oh, if you are making a new patch, you might consider making it so if info is null, just immediately
return.  Then you don't have to right-shift the whole body of the method (YOur patch will
be smaller too).  Thanks.
