Prasanth Jayachandran commented on HIVE-12935:
----------------------------------------------
Tested this patch on 1TB scale q55-random.sql queries with chaosmonkey interval
of 120s on 6 instances. However I did not see any logs related to chaosmonkey
terminating an instance. The entire queryset succeeded though without any
issues. I also ran the same test with slider flexing up/down the number of
containers and was able to see the notifications. All queries succeeded while
flexing up and down (with few attempt failures/kills which are expected on
flexing down).

> Existing YARN registry service for cluster membership has to depend on
> refresh intervals to get the list of instances/daemons that are running in
> the cluster. Better approach would be replace it with zookeeper based
> registry service so that custom listeners can be added to update healthiness
> of daemons in the cluster.
