Might even be good to sketch your approach/design if possible to start the
discussion.
> YARN - topology information
> ----------------------------

> Key: SPARK-16878
> URL: https://issues.apache.org/jira/browse/SPARK-16878
> Project: Spark
> Issue Type: Sub-task
> Components: YARN
> Reporter: Shubham Chopra

> Block replication strategies need topology information for ideal block
> placements. This information is available in resource managers and/or can be
> provided separately through scripts/services/classes, as in the case of HDFS.
> This jira focuses on enhancing spark-yarn package to suitably extract
> topology information from YARN.
