Subject [jira] [Commented] (HBASE-16498) NPE when Scan's stopRow is set NULL
Date Sat, 27 Aug 2016 05:12:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15440714#comment-15440714
] 

ramkrishna.s.vasudevan commented on HBASE-16498:
------------------------------------------------

@pankaj as I said initially people are not convinced in setting null as it is wrong usage.
So better throw exception as per the prev comment. I thought it is fine but others are not
ok with it and it makes sense too.
