> DefaultSpeculator generates error messages on normal shutdown
> -------------------------------------------------------------
>
> Key: MAPREDUCE-4794
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4794
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: applicationmaster
> Affects Versions: 0.23.3, 2.0.1-alpha
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Attachments: MAPREDUCE-4794.patch

>
> DefaultSpeculator can log the following error message on a normal shutdown of
> the ApplicationMaster:
> {noformat}
> 2012-11-13 01:35:31,841 ERROR [DefaultSpeculator background processing]
> org.apache.hadoop.mapreduce.v2.app.speculate.DefaultSpeculator: Background
> thread returning, interrupted : java.lang.InterruptedException
> {noformat}
> and in addition for some reason it logs the corresponding backtrace to stdout.
> Like the errors fixed in MAPREDUCE-4741, this error message in the syslog and
> backtrace on stdout can be confusing to users as to whether the job really
> succeeded.
