Jacek Laskowski created SPARK-12267:
---------------------------------------
Summary: 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}}.
