      Description

      ProcfsBasedProcessTree has a habit of emitting not-so-helpful messages such as the following:

      2013-03-13 12:41:51,957 INFO [communication thread] org.apache.hadoop.yarn.util.ProcfsBasedProcessTree: The process 28747 may have finished in the interim.
      2013-03-13 12:41:51,958 INFO [communication thread] org.apache.hadoop.yarn.util.ProcfsBasedProcessTree: The process 28978 may have finished in the interim.
      2013-03-13 12:41:51,958 INFO [communication thread] org.apache.hadoop.yarn.util.ProcfsBasedProcessTree: The process 28979 may have finished in the interim.
      

      As described in MAPREDUCE-4570, this is something that naturally occurs in the process of monitoring processes via procfs. It's uninteresting at best and can confuse users who think it's a reason their job isn't running as expected when it appears in their logs.

      We should either make this DEBUG or remove it entirely.
