> Validate heartheat arguments in HeartbeatReceiver
> -------------------------------------------------
>
> Key: SPARK-26530
> URL: https://issues.apache.org/jira/browse/SPARK-26530
> Project: Spark
> Issue Type: Improvement
> Components: Deploy, Spark Core
> Affects Versions: 2.3.2, 2.4.0
> Reporter: liupengcheng
> Assignee: liupengcheng
> Priority: Major
> Fix For: 3.0.0
>
>
> Currently, heartbeat related arguments is not validated in spark, so if these
> args are inproperly specified, the Application may run for a while and not
> failed until the max executor failures reached(especially with
> spark.dynamicAllocation.enabled=true), thus may incurs resources waste.
> We shall do validation before submit to cluster.
