Jason Lowe created YARN-476: ------------------------------- Summary: ProcfsBasedProcessTree info message confuses users Key: YARN-476 URL: https://issues.apache.org/jira/browse/YARN-476 Project: Hadoop YARN Issue Type: Bug Affects Versions: 0.23.6 Reporter: Jason Lowe
ProcfsBasedProcessTree has a habit of emitting not-so-helpful messages such as the following: {noformat} 2013-03-13 12:41:51,957 INFO [communication thread] org.apache.hadoop.yarn.util.ProcfsBasedProcessTree: The process 28747 may have finished in the interim. 2013-03-13 12:41:51,958 INFO [communication thread] org.apache.hadoop.yarn.util.ProcfsBasedProcessTree: The process 28978 may have finished in the interim. 2013-03-13 12:41:51,958 INFO [communication thread] org.apache.hadoop.yarn.util.ProcfsBasedProcessTree: The process 28979 may have finished in the interim. {noformat} As described in MAPREDUCE-4570, this is something that naturally occurs in the process of monitoring processes via procfs. It's uninteresting at best and can confuse users who think it's a reason their job isn't running as expected when it appears in their logs. We should either make this DEBUG or remove it entirely. -- This message is automatically generated by JIRA.
