Subject [jira] Commented: (MAPREDUCE-1283) Support including 3rd party jars supplied in lib/ folder of eclipse project in hadoop jar

Amit Nithian commented on MAPREDUCE-1283:
-----------------------------------------

Thanks for the vote and comment. Maybe i'm wrong.. I am not that familiar with the internals
of hadoop job submission but doesn't it only respect jars located in the lib/ folder? I didn't
want to include all jars on the classpath because as you said this could be a lot so what
I tend to do is segment my jars into lib and third-party and add both folders' jars to my
classpath. i am open to suggestions on configurability but I want to make sure my jar isn't
bloated with useless jars too.

> Currently, the eclipse plugin only exports the generated class files to the hadoop jar
but if there are any 3rd party jars specified in the lib/ folder, they should also get packaged
in the jar for submission to the cluster. Currently this has to be done manually which can
slow down development. I am working on a patch to the current plugin to support this.
