dhruba borthakur commented on MAPREDUCE-1218:
---------------------------------------------

Thanks for your comments Hong. I agree that an external piece of monitoring software has its
own set of advantages (and disadvantages).

Based on this discussion, do we move ProcfsBasedProcessTree.java from the mapreduce subproject
to the common subproject?
