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.
