Vinod Kumar Vavilapalli commented on MAPREDUCE-3390:
----------------------------------------------------
I am fine with the patch as is. But I am skeptical that it will fix any issue.
The generated-classpath file should always be there in the jars and you
shouldn't be hitting this at all. Unless you are running into random jar
related issues like staleness. Can you please confirm?
