[jira] [Created] (MAPREDUCE-4570)
ProcfsBasedProcessTree#constructProcessInfo() prints a warning if
procfsDir//stat is not found.
Ahmed Radwan created MAPREDUCE-4570:
---------------------------------------
Summary: ProcfsBasedProcessTree#constructProcessInfo() prints a warning if procfsDir/<pid>/stat is not found.
Key: MAPREDUCE-4570
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4570
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Reporter: Ahmed Radwan
Assignee: Ahmed Radwan
Priority: Minor
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.

------------------------------------------------
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.

> 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.
