Andrew Or updated SPARK-6469:
-----------------------------
Component/s: Documentation
> Improving documentation on YARN local directories usage
> -------------------------------------------------------
>
> Key: SPARK-6469
> URL: https://issues.apache.org/jira/browse/SPARK-6469
> Project: Spark
> Issue Type: Documentation
> Components: Documentation, YARN
> Affects Versions: 1.0.0
> Reporter: Christophe Préaud
> Assignee: Christophe Préaud
> Priority: Minor
> Fix For: 1.3.1, 1.4.0
>
> Attachments: TestYarnVars.scala
>
>
> According to the [Spark YARN doc
> page|http://spark.apache.org/docs/latest/running-on-yarn.html#important-notes],
> Spark executors will use the local directories configured for YARN, not
> {{spark.local.dir}} which should be ignored.
> However it should be noted that in yarn-client mode, though the executors
> will indeed use the local directories configured for YARN, the driver will
> not, because it is not running on the YARN cluster; the driver in yarn-client
> will use the local directories defined in {{spark.local.dir}}
> Can this please be clarified in the Spark YARN documentation above?
