Christophe PRÉAUD commented on SPARK-6469:
------------------------------------------
Sure, I will take care of this.
> The YARN driver in yarn-client mode will not use the local directories configured for
YARN
> -------------------------------------------------------------------------------------------

> Key: SPARK-6469
> URL: https://issues.apache.org/jira/browse/SPARK-6469
> Project: Spark
> Issue Type: Documentation
> Components: YARN
> Reporter: Christophe PRÉAUD
> Priority: Minor
> 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?
