Subject [jira] [Commented] (HBASE-8433) CellComparator#compare returns incorrect result for faked KeyValue
Date Thu, 25 Apr 2013 04:54:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8433?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13641422#comment-13641422

ramkrishna.s.vasudevan commented on HBASE-8433:
-----------------------------------------------

This is basically the check that is missed out when the CellComparator was implemented.
KeyValueComparator has this already.  
When we have to move from KV to Cell based impl these are some areas that we may have to look
for so. Thanks Chunhui.
