Subject [jira] [Commented] (PIG-3285) Jobs using HBaseStorage fail to ship dependency jars
Date Fri, 15 Nov 2013 22:33:20 GMT

    [ https://issues.apache.org/jira/browse/PIG-3285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13824186#comment-13824186

Jarek Jarcec Cecho commented on PIG-3285:

I really do like idea behind this patch, thank you for driving the effort on both sides  [~ndimiduk]!
Do you think that we can leave the older code laying around for couple of Pig releases and
switch between those two conditionally based on the HBase version? I'm concerned a bit about
backward compatibility here as this patch will make pig not working on a HBase releases where
it is currently working.
