> ---------------------------------------------------------------------------------------

> Key: SPARK-24954
> URL: https://issues.apache.org/jira/browse/SPARK-24954
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.4.0
> Reporter: Jiang Xingbo
> Priority: Blocker
>
> Since we explicitly listed "Support running barrier stage with dynamic
> resource allocation" a Non-Goal in the design doc, we shall fail fast on job
> submit if running a barrier stage with dynamic resource allocation enabled,
> to avoid some confusing behaviors (can refer to SPARK-24942 for some
> examples).
