Subject [jira] [Commented] (YARN-1039) Add parameter for YARN resource requests to indicate "long lived"
Date Fri, 20 Jun 2014 01:41:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-1039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14038248#comment-14038248
] 

Vinod Kumar Vavilapalli commented on YARN-1039:
-----------------------------------------------

For now, we can start with a parameter on the ApplicationSubmissionContext - we are still
figuring out long-running services before delving into enabling a smaller subset of long-lived
containers within a larger application..

> A container request could support a new parameter "long-lived". This could be used by
a scheduler that would know not to host the service on a transient (cloud: spot priced) node.
> Schedulers could also decide whether or not to allocate multiple long-lived containers
on the same node
