-Re: Error starting MRAppMaster

This has got nothing to do with the scheduler.
I believe this has got to do with some compilation issue. How did you build hadoop?
Also, I found that the repo at github (which is a mirror of git repo at apache) doesn't always pick all the commits immediately. You are better off checking out from svn (http://hadoop.apache.org/common/version_control.html)
