Sean Owen commented on SPARK-1640:
----------------------------------
[~sandyr] is this still relevant given more recent work on YARN data locality?
> In yarn-client mode, pass preferred node locations to AM

> Key: SPARK-1640
> URL: https://issues.apache.org/jira/browse/SPARK-1640
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 0.9.0
> Reporter: Sandy Ryza
>
> In yarn-cluster mode, if the user passes preferred node location data to the
> SparkContext, the AM requests containers based on that data.
> In yarn-client mode, it would be good to do this as well. This required some
> way of passing this data from the client process to the AM.
