Wenlong Lyu updated FLINK-16279:
--------------------------------
Description:
I run a job in yarn per job mode using {{env.executeAsync}}, the job failed but
the yarn cluster didn't be destroyed.
After some research on the code, I found that:
when running in attached mode, MiniDispatcher will never set {{shutDownfuture}}
before received a request from job client.
{code}
if (executionMode == ClusterEntrypoint.ExecutionMode.NORMAL) {
// terminate the MiniDispatcher once we served the
first JobResult successfully
jobResultFuture.thenAccept((JobResult result) -> {
ApplicationStatus status =
result.getSerializedThrowable().isPresent() ?
ApplicationStatus.FAILED :
ApplicationStatus.SUCCEEDED;
LOG.debug("Shutting down per-job cluster
because someone retrieved the job result.");
shutDownFuture.complete(status);
});
}
{code}
However, when running in async mode(submit job by env.executeAsync), there may
be no request from job client because when a user find that the job is failed
from job client, he may never request the result again.
