Subject [jira] [Commented] (YARN-6840) Leverage RMStateStore to store scheduler configuration updates
Date Fri, 21 Jul 2017 17:57:00 GMT

Naganarasimha G R commented on YARN-6840:
-----------------------------------------

[~wangda], 
Can help to check that out, IIUC Based on YARN-5947 LogMutations are the objects which are
stored in zk right ? Further we need to consider the case of partitions also as the whole
queue hierarchy mapping gets repeated for each partition. 
But as you said there would be decrease in size initially as the contents would get repeated
but if we plan to store mutations/updates only, then compression might not be of any help
for mutations !

> With this change, user doesn't have to setup separate storage system (like LevelDB) to
store updates of scheduler configs. And dynamic queue can be used when RM HA is enabled.
