LinuxTaskController binary should be versioned and mapreduce should run only with a particular
version
------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-976
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-976
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
            Reporter: Vinod K V


There is a strict coupling between the mapreduce code and the LinuxTaskController binary that
it runs. Accidentally/intentionally running different versions of the binary with different
versions of the framework may lead to hard-to-debug problems. We should have checks similar
to JT-TT version lock-in.
