> 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?
