> The logic in the TaskTracker and the DataNode to allow a relax version check with the JobTracker and NameNode is not working.
> The relaxed check is done after the strict check, thus no chance for the relaxed check to ever happen.
> The relaxed check is hardcoded to require exact same versions (allowing different builds). The relaxed check should be able to work with a prefix of the full version (i.e. to handle patch releases).
