ajithme opened a new pull request #24056: [SPARK-26152] Synchronize Worker Cleanup with Worker Shutdown
URL: https://github.com/apache/spark/pull/24056
## What changes were proposed in this pull request?
The race between org.apache.spark.deploy.DeployMessages.WorkDirCleanup event and org.apache.spark.deploy.worker.Worker#onStop. Here its possible that while the WorkDirCleanup event is being processed, org.apache.spark.deploy.worker.Worker#cleanupThreadExecutor was shutdown. hence any submission after ThreadPoolExecutor will result in java.util.concurrent.RejectedExecutionException
## How was this patch tested?
Manually
