Subject [jira] [Commented] (YARN-1011) [Umbrella] Schedule containers based on utilization of currently allocated containers
Date Fri, 14 Jul 2017 18:55:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-1011?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16087794#comment-16087794
] 

Wangda Tan commented on YARN-1011:
----------------------------------

Thanks [~kasha] / [~haibo.chen] for the proposal.  

I just left some comments in YARN-6808: https://issues.apache.org/jira/browse/YARN-6808?focusedCommentId=16087782&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16087782
It may related to this feature as well, so could you please take a look when you have time?


I think it might be better to move some JIRAs to a new umbrella: "improve using opportunistic
container for normal use cases". YARN-1014/YARN-6674 like I suggested in YARN-6808.

Thoughts?

> Currently RM allocates containers and assumes resources allocated are utilized.
> RM can, and should, get to a point where it measures utilization of allocated containers
and, if appropriate, allocate more (speculative?) containers.
