Subject [jira] [Created] (YARN-476) ProcfsBasedProcessTree info message confuses users
Date Wed, 13 Mar 2013 22:48:16 GMT
Jason Lowe created YARN-476:
-------------------------------

             Summary: ProcfsBasedProcessTree info message confuses users
                 Key: YARN-476
                 URL: https://issues.apache.org/jira/browse/YARN-476
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 0.23.6
            Reporter: Jason Lowe


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

{noformat}
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.
{noformat}

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.
