["Jarek Jarcec Cecho (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-3002?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jarek Jarcec Cecho updated PIG-3002:
------------------------------------

    Attachment: PIG-3002.patch

I've tried to fix this issue by moving code that is responsible for getting counter value to shim layer. By doing this I can properly catch CountersExceededException only for Hadoop 0.23 and higher.

My current patch do not include any tests as I'm not sure where to put shim related tests. I did however verified the functionality on real clusters with Hadoop 1.x and Hadoop 2.x.
