[jira] [Commented] (YARN-7086) Release all containers aynchronously

 ] 

Manikandan R commented on YARN-7086:


[~jlowe] Thanks for very detailed suggestion.
{quote}I'm worried that we're delving into the classic pitfall of optimizing 
without profiling data or hands-on experience to prove the optimizations make 
sense.{quote}Sorry about this. My understanding from earlier discussion is that 
there would be potential performance degradation with LeafQueue lock for sure 
and acquiring lock only once was mandatory for releasing batch of containers. 
Hence I went with this trade off (multiple container list traversal). Now that 
we are interested in doing the next step based on stress test (which is good 
for decision making), I will take a look on TestCapacitySchedulerPerf and 
perform the tests. Based on the numbers, as you suggested, it can help us to 
define the next steps clearly.

> We have noticed in production two situations that can cause deadlocks and 
> cause scheduling of new containers to come to a halt, especially with regard 
> to applications that have a lot of live containers:
> # When these applicaitons release these containers in bulk.
> # When these applications terminate abruptly due to some failure, the 
> scheduler releases all its live containers in a loop.
> To handle the issues mentioned above, we have a patch in production to make 
> sure ALL container releases happen asynchronously - and it has served us well.
> Opening this JIRA to gather feedback on if this is a good idea generally (cc 
> [~leftnoteasy], [~jlowe], [~curino], [~kasha], [~subru], [~roniburd])
> BTW, In YARN-6251, we already have an asyncReleaseContainer() in the 
> AbstractYarnScheduler and a corresponding scheduler event, which is currently 
> used specifically for the container-update code paths (where the scheduler 
> realeases temp containers which it creates for the update)

[~jlowe] [~leftnoteasy] Thanks for your comments.

Addressed the following:

1. Introduced init, stop, addNode, removeNode methods in interface to handle 
the cases described in earlier comment. 

2. Introduced refreshConfigs as described in earlier comment.

3. Kept the plugin interactions into each of the schedulers.

{quote}Back to the prototype patch, I assume NodeHeartBeatPluginImpl is just an 
example and would not be part of the final commit?{quote}

Yes, thats the initial thought. But then, was thinking to mould it as concrete 
implementation at least for one scheduler (for ex, say CS) so that it can act 
as well defined example for future plugin development. Hence asked you to 
suggest potential movable code parts from CS scheduler. Thoughts?

Also, Where shall we keep the plugin? RMActiveService? or Scheduler like 
[~leftnoteasy] suggested earlier?
