Subject [jira] [Commented] (PIG-4426) RowNumber(simple) Rank not producing correct results
Date Wed, 25 Feb 2015 15:20:04 GMT

    [ https://issues.apache.org/jira/browse/PIG-4426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14336605#comment-14336605

Koji Noguchi commented on PIG-4426:
-----------------------------------

+1 on moving away from counter based approach. (I believe Tez version of Rank already does
that.)
