Apache Spark reassigned SPARK-35627:
------------------------------------
Assignee: Apache Spark
> Decommission executors in batches to avoid overloading network by block
> migrations.
> -----------------------------------------------------------------------------------
>
> Key: SPARK-35627
> URL: https://issues.apache.org/jira/browse/SPARK-35627
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 3.1.2
> Reporter: abhishek kumar tiwari
> Assignee: Apache Spark
> Priority: Major
>
> Currenlty, each executor is asked to starts offloading rdd and shuffle blocks
> as soon it is decommissioned. This can overload the network bandwidth of the
> application.
>
> We should limit the number of executors migrating rdd and shuffle blocks at
> one time. This would be configurable to enable users to decommission
> executors conservatively or aggressively based on the use cases.
