Subject [jira] [Commented] (PHOENIX-3769) OnDuplicateKeyIT#testNewAndMultiDifferentUpdateOnSingleColumn fails on ppc64le
Date Fri, 04 Aug 2017 10:14:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16114210#comment-16114210

Sneha Kanekar commented on PHOENIX-3769:
----------------------------------------

I found another workaround for this issue. I noticed that the respective lengths of the arrays
are not passed to compareTo function. On making this change, the test passes on ppc64le as
well as x86.
