Subject [jira] [Commented] (PHOENIX-4534) upsert/delete/upsert for the same row corrupts the indexes
Date Thu, 03 May 2018 16:22:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-4534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16462705#comment-16462705
] 

James Taylor commented on PHOENIX-4534:
---------------------------------------

I'm not seeing this committed to any of the 4.x or master branches. Is it needed, [~rajeshbabu],
[~elserj], [~sergey.soldatov]? Sounds like it's need maybe only in master which is on HBase
1.4?
