Re: Use hadoop.relaxed.worker.version.check to allow versions in the same major version?
Hey Karthik, We already support this for HDFS, see HDFS-2983 (Relax the build version check to permit rolling upgrades within a release). We should do so for Yarn as well, MAPREDUCE-4150 tracks this. I don't think Ahmed is working on it so would be great for you or someone else to take it.

The motivation for this is rolling upgrade within a major release. We could use the same property hadoop.relaxed.worker.version.check for this or add another property. Thoughts? Thanks Karthik

Thanks for the pointers, Eli. Glad HDFS already takes care of this - I ll follow up on the MR JIRA.
