Will investigate
> Standalone master keeps references to disassociated workers until they sent
> no heartbeats
> -----------------------------------------------------------------------------------------
>
> Key: SPARK-12267
> URL: https://issues.apache.org/jira/browse/SPARK-12267
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.6.0
> Reporter: Jacek Laskowski
>
> While toying with Spark Standalone I've noticed the following messages
> in the logs of the master:
> {code}
> INFO Master: Registering worker 192.168.1.6:59919 with 2 cores, 2.0 GB RAM
> INFO Master: localhost:59920 got disassociated, removing it.
> ...
> WARN Master: Removing worker-20151210090708-192.168.1.6-59919 because
> we got no heartbeat in 60 seconds
> INFO Master: Removing worker worker-20151210090708-192.168.1.6-59919
> on 192.168.1.6:59919
> {code}
> Why does the message "WARN Master: Removing
> worker-20151210090708-192.168.1.6-59919 because we got no heartbeat in
> 60 seconds" appear when the worker should've been removed already (as
> pointed out in "INFO Master: localhost:59920 got disassociated,
> removing it.")?
> Could it be that the ids are different - 192.168.1.6:59919 vs localhost:59920?
> I started master using {{./sbin/start-master.sh -h localhost}} and the
> workers {{./sbin/start-slave.sh spark://localhost:7077}}.
