Summary: Spark application hangs when YarnAllocator adds running executors
after processing completed containers (was: Spark application hangs when
YarnAllocator adding running executors after processing completed containers)
> Spark application hangs when YarnAllocator adds running executors after

> Key: SPARK-43510
> URL: https://issues.apache.org/jira/browse/SPARK-43510
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 3.4.0
> Reporter: Manu Zhang
> Priority: Major
>
> I see application hangs when containers are preempted immediately after
> allocation as follows.
> {code:java}

> container_e3812_1684033797982_57865_01_000382 was preempted.{code}
> Note the warning log where YarnAllocator cannot find executorId for the
> container when processing completed containers. The only plausible cause is
> YarnAllocator added the running executor after processing completed
> containers. The former happens in a separate thread after executor launch.
> YarnAllocator believes there are still running executors, although they are
> already lost due to preemption. Hence, the application hangs without any
> running executors.
