Subject [jira] [Commented] (HBASE-18368) Filters with OR does not work
Date Wed, 12 Jul 2017 16:14:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16084242#comment-16084242
] 

Allan Yang commented on HBASE-18368:
------------------------------------

Did some research, this bug may not be introduced by HBASE-17678, but by HBASE-13122. Upload
a patch to fix this. We shouldn't return NEXT_ROW when FamilyFilter doesn't match.

for only the first Filter.
