Subject [jira] [Commented] (SPARK-12267) Standalone master keeps references to disassociated workers until they sent no heartbeats
Date Thu, 10 Dec 2015 21:45:10 GMT

    [ https://issues.apache.org/jira/browse/SPARK-12267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15051700#comment-15051700

Marcelo Vanzin commented on SPARK-12267:
----------------------------------------

[~shixiong@databricks.com] you're right but that's the wrong PR you picked; I think this is
a side-effect of SPARK-10997.

Still trying to figure out the best way to fix this.

>             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}}.
