Status: Patch Available (was: Open)
> Should kill running Spark Jobs when a query is cancelled.
> ---------------------------------------------------------

> Key: HIVE-16422
> URL: https://issues.apache.org/jira/browse/HIVE-16422
> Project: Hive

> Should kill running Spark Jobs when a query is cancelled. When a query is
> cancelled, Driver.releaseDriverContext will be called by Driver.close.
> releaseDriverContext will call DriverContext.shutdown which will call all the
> running tasks' shutdown.
> {code}
> public synchronized void shutdown() {
> LOG.debug("Shutting down query " + ctx.getCmd());
> shutdown = true;
> for (TaskRunner runner : running) {
> if (runner.isRunning()) {
> Task<?> task = runner.getTask();
> LOG.warn("Shutting down task : " + task);
> try {
> task.shutdown();
> } catch (Exception e) {
> console.printError("Exception on shutting down task " +
> task.getId() + ": " + e);
> }
> Thread thread = runner.getRunner();
> if (thread != null) {
> thread.interrupt();
> }
> }
> }
> running.clear();
> }
> {code}
> since SparkTask didn't implement shutdown method to kill the running spark
> job, the spark job may be still running after the query is cancelled. So it
> will be good to kill the spark job in SparkTask.shutdown to save cluster
> resource.
