Sandy Ryza updated SPARK-3560:
------------------------------
Component/s: YARN
> In yarn-cluster mode, jars are distributed through multiple mechanisms.
> -----------------------------------------------------------------------
>
> Key: SPARK-3560
> URL: https://issues.apache.org/jira/browse/SPARK-3560
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Reporter: Sandy Ryza
> Priority: Critical
>
> In yarn-cluster mode, jars given to spark-submit's --jars argument should be
> distributed to executors through the distributed cache, not through fetching.
> Currently, Spark tries to distribute the jars both ways, which can cause
> executor errors related to trying to overwrite symlinks without write
> permissions.
> It looks like this was introduced by SPARK-2260, which sets spark.jars in
> yarn-cluster mode. Setting spark.jars is necessary for standalone cluster
> deploy mode, but harmful for yarn cluster deploy mode.
