[jira] [Commented] (PIG-2353) RANK function like in SQL

    [ https://issues.apache.org/jira/browse/PIG-2353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447590#comment-13447590 ] 

Gianmarco De Francisci Morales commented on PIG-2353:
-----------------------------------------------------

There is a regression in the latest patch.
It does not work properly in a multi-machine environment.
It seems that the values of the counters are not properly serialized in the JobConf.
We need to add a test and fix the bug before committing the patch.
