Subject [jira] [Updated] (MAPREDUCE-3087) CLASSPATH not the same after MAPREDUCE-2880

Ravi Prakash updated MAPREDUCE-3087:
------------------------------------

    Attachment: MAPREDUCE-3087.patch

Arun. It was a blocker for me to do any dev work because all my jobs were failing

I don't know if we ever want to have something in the CLASSPATH which doesn't make sense to
the JVM, and /somepath/mr-apps.jar!/mrapp-generated-classpath doesn't make sense to the JVM
(so it will be ignored).

Please ignore the last patch. It was an attempt to include tests, but it seems pretty hard
because:
1. If I include the real mr-app.jar (using pom.xml), then a circular dependency is created.
2. If I don't include the mr-app.jar, then I must checkin and include in the CLASSPATH some
jar containing a file mrapp-generated-classpath. This seemed too much effort for a simple
one line change.

I'm re-uploading the 1st patch with is a single line change.
