Alejandro Abdelnur updated YARN-910:
------------------------------------
Attachment: YARN-910.patch
[~vinodkv], thanks for your feedback.
I'd like to keep the current behavior that INIT & STOP always come in pairs. It
will make things easier for aux services implementations.
I've modified the IF to check if the current state is not NEW, unless I'm
missing something this addresses the scenario you pointed out:
{code}
if (container.getCurrentState()
!= org.apache.hadoop.yarn.api.records.ContainerState.NEW) {
{code}
> Allow auxiliary services to listen for container starts and completions

> Making container start and completion events available to auxiliary services
> would allow them to be resource-aware. The auxiliary service would be able
> to notify a co-located service that is opportunistically using free capacity
> of allocation changes.
