Subject [jira] [Commented] (HBASE-6048) Table Scan is failing if offheap cache enabled
Date Fri, 24 Jan 2014 04:50:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6048?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13880714#comment-13880714

ramkrishna.s.vasudevan commented on HBASE-6048:
-----------------------------------------------

I think we need to fix this.
See the mail thread
http://mail-archives.apache.org/mod_mbox/hbase-user/201401.mbox/%3C52DECFD2.4040600@gmail.com%3E
As per the user the off heap cache though being experimental was getting used by them in 0.92
and did not see it was broken.  but in 0.94 it seems to be broken.
[~zjushch]
Do you have a fix for this by any chance?  I think it is worth solving for users like Dean.
Thoughts?
