Subject [jira] [Commented] (YARN-5031) Add a conf to disable container reservation
Date Tue, 03 May 2016 12:51:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-5031?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15268642#comment-15268642

Sunil G commented on YARN-5031:

Container reservation is by far helps in many cases. In a heterogeneous cluster, where different
types applications were running, I am not very sure about a configuration which disables reservation
in scheduler level. As per the use case, this scenario looks like more of application specific.
Since queues gives only a logical view of resources, and reservation happens on node, we need
to see how better output we can get for a queue level config. 
A suggestion, I feel preemption can help here if in case queue is under served and other queues
requests were reserved on node. Thoughts?
