>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: tasktracker
>            Reporter: Vinod Kumar Vavilapalli

> 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.
