Zhijie Shen commented on YARN-926:
----------------------------------
bq. Similarly the client library needs to be modified - may be we can have both
single container and multi-container APIs in the clients.
In NMClientAsync, it will be interesting to see whether it is good to gather a
number of single container starting requests, combine them, and send a batch
request.
Another question, should stopContainer take the request of multiple containers
as well?
> ContainerManagerProtcol APIs should take in requests for multiple containers

> AMs typically have to launch multiple containers on a node and the current
> single container APIs aren't helping. We should have all the APIs take in
> multiple requests and return multiple responses.
> The client libraries could expose both the single and multi-container
> requests.
