> Task failures during shutdown cause problems with preempted executors
> ---------------------------------------------------------------------
>
> Key: SPARK-20904
> URL: https://issues.apache.org/jira/browse/SPARK-20904
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, YARN
> Affects Versions: 1.6.0
> Reporter: Marcelo Vanzin
> Fix For: 2.2.1, 2.3.0
>
>
> Spark runs tasks in a thread pool that uses daemon threads in each executor.
> That means that when the JVM gets a signal to shut down, those tasks keep
> running.
> Now when YARN preempts an executor, it sends a SIGTERM to the process,
> triggering the JVM shutdown. That causes shutdown hooks to run which may
> cause user code running in those tasks to fail, and report task failures to
> the driver. Those failures are then counted towards the maximum number of
> allowed failures, even though in this case we don't want that because the
> executor was preempted.
> So we need a better way to handle that situation.
