Hi. I'm currently running a Hadoop cluster on Amazon's EMR service, which appears to be the 0.20.2 codebase plus several patches from the (deprecated?) 0.20.3 branch. I'm interested in switching from using the fair scheduler to the capacity scheduler, but I'm also interested in the user-limit-factor configuration parameter introduced in 0.20.203. This parameter is not available in the EMR-supplied capacity scheduler jar, so I was wondering if it's possible and safe to drop the 0.20.203 capacity scheduler jar into my Hadoop library path.
Any information would be very helpful. Thanks! Kai Ju
