Subject [jira] [Commented] (PIG-3199) Expose LogicalPlan via PigServer API
Date Fri, 22 Feb 2013 23:22:13 GMT

    [ https://issues.apache.org/jira/browse/PIG-3199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13584808#comment-13584808

Alan Gates commented on PIG-3199:
---------------------------------

Take a look at PigNotificationListener.initialPlanNotification.  It seems like this will give
you what you want, since each of the sources and sinks for the MR jobs are in here.  To my
chagrin this exposes the MR plan.  Someone snuck that past me.

> LogicalPlan could be exposed to user in order for one to make validations based on it.
For eg, one could get Load/Store paths or other operators and be able to perform checks such
as whether I/O paths are valid etc.
