-----------------------------------------------
I think we need to fix this.
See the mail thread
http://mail-archives.apache.org/mod_mbox/hbase-user/201401.mbox/%3c52decfd2.4040...@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.

Do you have a fix for this by any chance? I think it is worth solving for
users like Dean.
Thoughts?
