[jira] [Commented] (PIG-3430) Add xml format for explaining MapReduce Plan.

    [ https://issues.apache.org/jira/browse/PIG-3430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13753350#comment-13753350 ] 

Daniel Dai commented on PIG-3430:
---------------------------------

I can get xml mapreduce plan with the patch. Two questions:
1. Any reason we only do it in mapreduce plan?
2. Why we need to mark tmpLoader? Is it to support xml mapreduce plan? Or it is a separate thing?

> At Mortar we needed an easy way to store/parse a script's map reduce plan.  We added an xml output format for the MapReduce plan to make this easier.  We also added a flag to keep track of if each store or load was from the original script (and associated with an alias) or if its a temporary store/load generated by Pig.
