Subject [jira] [Commented] (YARN-1039) Add parameter for YARN resource requests to indicate "long lived"
Date Tue, 20 Jan 2015 19:28:36 GMT

    [ https://issues.apache.org/jira/browse/YARN-1039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14284265#comment-14284265

Jian Fang commented on YARN-1039:
---------------------------------

Thanks Carlo, the notion of duration does make sense in certain scenarios. But the actual
duration parameter in a running cluster is probably very difficult to measure if not impossible.
For example, the duration could be affected by cluster size, workload, retry logic, scheduling
algorithm, network and IO contention and so on.

> 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
