Subject [jira] [Commented] (CRUNCH-160) CrunchInputFormat needs to create a new Configuration object for each delegate InputFormat

Micah Whitacre commented on CRUNCH-160:
---------------------------------------

+1 for the patch. Applied it locally and ran with the CDH4 dependency set which was previously
failing and it now works correctly.  Thanks for tracking this down.

> In Hadoop 2.x.x, the Job object no longer creates a copy of a Configuration object that
it is passed. This is a problem for the CrunchInputFormat, which assumes that it does (as
it does in Hadoop 1.0.x). We need to update the CrunchInputFormat to create a copy of the
Configuration object itself and configure it before passing it to a new Job object.
