Description:
Hi, we have a long-lived Spark application run on a standalone cluster on GCP
and we are using spot instances. To reduce the impact of preempted instances,
we have enabled node decommission to let the preempted node migrate its shuffle
data to other instances before it is deleted by GCP.
However, we found the migrated shuffle data from the decommissioned node is
never removed. (same behavior on spark-3.5)
*Reproduce steps:*
1. Start spark-shell with 3 executors and enable decommission on both
driver/worker
{code:java}
start-worker.sh[3331]: Spark Command:
/usr/lib/jvm/java-17-openjdk-amd64/bin/java -cp

2. Manually stop 1 worker during execution

val df = (1 to 1 * i).map(j => (j, s"${j}_${longString}")).toDF("id",
"mystr")
df.repartition(6).count()
System.gc()

Thread.sleep(15*1000)

System.gc()

Description:
Hi, we have a long-lived Spark application run on a standalone cluster on GCP
and we are using spot instances. To reduce the impact of preempted instances,
we have enabled node decommission to let the preempted node migrate its shuffle
data to other instances before it is deleted by GCP.
However, we found the migrated shuffle data from the decommissioned node is
never removed. (same behavior on spark-3.5)
*Reproduce steps:*
1. Start spark-shell with 3 executors and enable decommission on both
driver/worker

2. Manually stop 1 worker during execution
