Subject [jira] [Commented] (YARN-1039) Add parameter for YARN resource requests to indicate "long lived"
Date Mon, 19 Jan 2015 22:31:36 GMT

Xuan Gong commented on YARN-1039:
---------------------------------

bq. If that is true, shouldn't YARN-796 have already addressed this issue with a more generic
way to schedule containers based on tags/labels?
Yes, it is. But for node labeling, that is for resource scheduling. I think that the application
should also identify itself as long-live or short-live. If not, how the RM figure out which
resources I should assign to this 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
