    Description

      The current logic in the TaskTracker and the DataNode to allow a relax version check with the JobTracker and NameNode works only if the versions of Hadoop are exactly the same.

      We should add a switch to disable version checking completely, to enable rolling upgrades between compatible versions (typically patch versions).
