Subject [jira] [Commented] (YARN-2885) Create AMRMProxy request interceptor for distributed scheduling decisions for queueable containers
Date Fri, 04 Dec 2015 07:10:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-2885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15041176#comment-15041176
] 

Konstantinos Karanasos commented on YARN-2885:
----------------------------------------------

[~leftnoteasy], I think the Distributed Scheduler AM Service makes sense.

Given that we will already add the Distributed Scheduling Coordinator in the RM (which will
be used for the top-k technique, and later for the corrective mechanisms in YARN-2888), what
about using the same service for delegating the AMProtocol wrapper (rather than creating an
additional one)?

> We propose to add a Local ResourceManager (LocalRM) to the NM in order to support distributed
scheduling decisions. 
> Architecturally we leverage the RMProxy, introduced in YARN-2884. 
> The LocalRM makes distributed decisions for queuable containers requests. 
> Guaranteed-start requests are still handled by the central RM.
