Vinod Kumar Vavilapalli commented on YARN-2181:
-----------------------------------------------
Tx for the UI, it looks great!
Glanced at the patch, one comment - did not do a detailed review - we don't
usually name transitions based on what happens in it. For e.g.
UpdatePreemptionMetricsTransition should instead be called something like
ContainerFinishedTransition and other ContainerFinished***Transitions can
inherit or invoke it.
It's likely this patch will conflict with YARN-415, please have a look at it
and figure out the order of the patches. Thanks..
> Add preemption info to RM Web UI and add logs when preemption occurs

> We need add preemption info to RM web page to make administrator/user get
> more understanding about preemption happened on app, etc.
> And RM logs should have following properties:
> * Logs are retrievable when an application is still running and often flushed.
> * Can distinguish between AM container preemption and task container
> preemption with container ID shown.
> * Should be INFO level log.
