Subject [jira] [Commented] (YARN-6840) Leverage RMStateStore to store scheduler configuration updates
Date Wed, 19 Jul 2017 00:37:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6840?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16092405#comment-16092405
] 

Daniel Templeton commented on YARN-6840:
----------------------------------------

Are you sure that's a good idea?  We're already abusing ZK pretty badly with the amount of
junk we cram in there as is.  Zookeeper is pretty clear in the docs that it should not be
used as a general purpose data store.

> 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.
