Jon Bringhurst created YARN-3344:
------------------------------------
Summary: procfs stat file is not in the expected format warning
Key: YARN-3344
URL: https://issues.apache.org/jira/browse/YARN-3344
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 2.6.0
Reporter: Jon Bringhurst
Although this doesn't appear to be causing any functional issues, it is
spamming our log files quite a bit. :)
It appears that the regex in ProcfsBasedProcessTree doesn't work for all
/proc/<pid>/stat files.
Here's the error I'm seeing (sorry about the janky json formatted log message):
{noformat}
{
"source_host": "asdf",
"method": "constructProcessInfo",
"level": "WARN",
"message": "Unexpected: procfs stat file is not in the expected format for
process with pid 6953"
"file": "ProcfsBasedProcessTree.java",
"line_number": "514",
"class": "org.apache.hadoop.yarn.util.ProcfsBasedProcessTree",
},
}
{noformat}
And here's the basic info on process with pid 6953:
{noformat}
[asdf ~]$ cat /proc/6953/stat
