Can you post the job-configuration as well as the AM logs? Tx.

> Key: MAPREDUCE-6066
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6066
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: applicationmaster, scheduler
> Affects Versions: 3.0.0
> Reporter: Todd Lipcon
>
> I'm seeing a behavior on trunk with fair scheduler enabled where a
> speculative reduce attempt is getting run on the same node as its original
> attempt. This doesn't make sense -- the main reason for speculative execution
> is to deal with a slow node, so scheduling a second attempt on the same node
> would just make the problem worse if anything.
