> Key: SPARK-26758
> URL: https://issues.apache.org/jira/browse/SPARK-26758
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 2.4.0
> Environment: Spark Version:2.4
> Reporter: ABHISHEK KUMAR GUPTA
> Priority: Major
> Attachments: SPARK-26758.png
>
>
> Steps:
> 1. Submit Spark shell with below initial Executor 3, minimum Executor=0 and
> executorIdleTimeout=60s
> {code}
> bin/spark-shell --master yarn --conf spark.dynamicAllocation.enabled=true \
> --conf spark.dynamicAllocation.initialExecutors=3 \
> --conf spark.dynamicAllocation.minExecutors=0 \
> --conf spark.dynamicAllocation.executorIdleTimeout=60s
> {code}
> 2. Launch Spark UI and check under Executor Tab
> Observation:
> Initial 3 Executors assigned. After 60s( executorIdleTimeout) , number of
> active executor remains same.
> Expected:
> Apart from AM container, all other executors should be dead.
