> Batch calls to RackResolver from AM
> -----------------------------------
>
> Key: MAPREDUCE-7070
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7070
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: applicationmaster, performance
> Reporter: Greg Phillips
> Priority: Minor
> Attachments: MAPREDUCE-7070.patch
>
>
> TaskAttemptImpl calls RackResolver once for every split location. This
> results in many shells being spawned by the Application Master when the
> topology script is enabled. The worst case scenario would entail one call to
> the topology script for each Datanode. The NameNode is also topology aware,
> and uses batch calls to the topology script to improve performance.
