Sunil G commented on YARN-3940:
-------------------------------
Sorry for pitching in late.
I thought of discussing a scenario here. I know [~leftnoteasy] and
[~bibinchundatt] were trying to make simpler implementation before clear
usecases are available.
But one scenario popped up while I was checking a recent issue from Jason
YARN-5540. Assume an application's AM containers was given a specific node
label and it got allocated. Now moveToQueue is performed, eventhough there are
no pending resource requests on AM container any more, I think as per current
impl will block move queue. This is because {{requestedPartitions}} is not
cleared with its ANY requests.
So I have 2 doubts:
- AM container allocated on label1. Now label1 is no more used by app1. Can
app1 be moved to a queue which does not *label1* as its labels.
- There were some out standing requests for a label called *label2*. But app
doesnt have any more outstanding there. This means that there are no containers
for this app is running on *label2*. Do we need to block this app from moving
to another queue which does nt have *label2*
I think its better to note this case for now some where so that we can track it
later. [~bibinchundatt] [~Naganarasimha Garla] thoughts?
