Subject [jira] [Created] (YARN-6510) Fix warning - procfs stat file is not in the expected format: YARN-3344 is not enough
Date Fri, 21 Apr 2017 18:14:04 GMT
Wilfred Spiegelenburg created YARN-6510:
-------------------------------------------

             Summary: Fix warning - procfs stat file is not in the expected format: YARN-3344
is not enough
                 Key: YARN-6510
                 URL: https://issues.apache.org/jira/browse/YARN-6510
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 3.0.0-alpha2, 2.8.0
            Reporter: Wilfred Spiegelenburg
            Assignee: Wilfred Spiegelenburg


Even with the fix for YARN-3344 we still have issues with the procfs format.

This is the case that is causing issues:
{code}
[user@nm1 ~]$ cat /proc/2406/stat
2406 (ib_fmr(mlx4_0)) S 2 0 0 0 -1 2149613632 0 0 0 0 166 126908 0 0 20 0 1 0 4284 0 0 18446744073709551615
0 0 0 0 0 0 0 2147483647 0 18446744073709551615 0 0 17 6 0 0 0 0 0
{code}

We do not handle the parenthesis in the name which causes the pattern matching to fail
