Dongjoon Hyun updated SPARK-26988:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Spark overwrites spark.scheduler.pool if set in configs
> -------------------------------------------------------
>
> Key: SPARK-26988
> URL: https://issues.apache.org/jira/browse/SPARK-26988
> Project: Spark
> Issue Type: Improvement
> Components: Scheduler
> Affects Versions: 3.1.0
> Reporter: Dave DeCaprio
> Priority: Minor
>
> If you set a default spark.scheduler.pool in your configuration when you
> create a SparkSession and then you attempt to override that configuration by
> calling setLocalProperty on a SparkSession, as described in the Spark
> documentation -
> [https://spark.apache.org/docs/latest/job-scheduling.html#fair-scheduler-pools]
> - it won't work.
> Spark will go with the original pool name.
> I've traced this down to SQLExecution.withSQLConfPropagated, which copies any
> key that starts with "spark" from the the session state to the local
> properties. The can end up overwriting the scheduler, which is set by
> spark.scheduler.pool
