[jira] [Commented] (YARN-6486) FairScheduler: Deprecate continuous scheduling in 2.9

["Arun Suresh (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-6486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16005078#comment-16005078 ] 

Arun Suresh commented on YARN-6486:
-----------------------------------

Any reason why you would want to deprecate this ?

Think we should unify Async Scheduling (from the Capacity Scheduler) and Continuous scheduling, since it looks pretty similar. Atleast the triggering thread can be made a common RM service.

There are some interesting scheduling performance improvements that can be done using a non-HB driven approach, coupled with time-based localilty relaxation that I've been experimenting with, both of which are offered by the Fair Scheduler. it would be sad to see this deprecated as a feature.

Thoughts ? (cc: [~kasha@cloudera.com], [~subru], [~leftnoteasy], [~curino])
