Wangda Tan commented on YARN-2314:
----------------------------------
[~jlowe], thanks for update, patch looks good to me, +1!
[~rajesh.balamohan], thanks for your performance report based on this. 20-30ms
is still a latency for interactive tasks cannot be totally ignored. At least,
we have way to cache connections via configuration option in this patch.

> ContainerManagementProtocolProxy has a cache of NM proxies, and the size of
> this cache is configurable. However the cache can grow far beyond the
> configured size when running on a large cluster and blow AM address/container
> limits. More details in the first comment.
