[jira] [Updated] (YARN-3344) procfs stat file is not in the
expected format warning
[ https://issues.apache.org/jira/browse/YARN-3344?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jon Bringhurst updated YARN-3344:
---------------------------------
Description:
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:
{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
