Robert Joseph Evans commented on MAPREDUCE-4570:
------------------------------------------------
The patch looks fine to me. +1 I just wish we could delete out the old mrv1
code so we don't have to maintain two copies.
> ProcfsBasedProcessTree#constructProcessInfo() prints a warning if
> procfsDir/<pid>/stat is not found.

> I think a warning is misleading in this case. What is happening here is that
> the list of all processes in the system is found, and then later the
> procfsDir/<pid>/stat file for each is opened. This warning is thrown when the
> process finishes before the stat file is opened, and hence the file is no
> longer there. This could normally happen, and shouldn't signify a waring. An
> info message is sufficient. I'll be uploading a patch momentarily.
