> Key: SPARK-37891
> URL: https://issues.apache.org/jira/browse/SPARK-37891
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.2.0
> Reporter: Tianhan Hu
> Assignee: Apache Spark
> Priority: Minor
> Fix For: 3.2.2
>
>
> Add scalastyle check to disable internal use of
> scala.concurrent.ExecutionContext.Implicits.global.
> The reason is that user queries can also use this thread pool, causing
> competing in resource and starvation. Spark-internal APIs should thus not use
> the global thread pool.
