      Description

      Currently there is version check on the RPC calls that enforces the same Hadoop version on the client and the server.

      To enable phased upgrades of systems using Hadoop and Hadoop itself the JobClient should be able to interact with a JobTracker of the previous and the next version of Hadoop (or with a range).
