> Fix supervised driver retry logic when agent crashes/restarts
> -------------------------------------------------------------
>
> Key: SPARK-27347
> URL: https://issues.apache.org/jira/browse/SPARK-27347
> Project: Spark
> Issue Type: Bug
> Components: Mesos
> Affects Versions: 2.2.1, 2.3.2, 2.4.0
> Reporter: Sam Tran
> Priority: Major
> Fix For: 2.3.4, 2.4.4, 3.0.0
>
>
> Ran into scenarios where {{--supervised}} Spark jobs were retried multiple
> times when an agent would crash, come back, and re-register even when those
> jobs had already relaunched on a different agent.
> That is:
> * supervised driver is running on agent1
> * agent1 crashes
> * driver is relaunched on another agent as `<task-id>-retry-1`
> * agent1 comes back online and re-registers with scheduler
> * spark relaunches the same job as `<task-id>-retry-2`
> * now there are two jobs running simultaneously and the first retry job is
> effectively orphaned within Zookeeper
> This is because when an agent comes back and re-registers, it sends a status
> update {{TASK_FAILED}} for its old driver-task. Previous logic would
> indiscriminately remove the {{submissionId from Zookeeper's launchedDrivers}}
> node and add it to {{retryList}} node.
> Then, when a new offer came in, it would relaunch another -retry task even
> though one was previously running.
> Sample log looks something like this:
> {code:java}
