Sounds reasonable.

> Currently, all the NMClient APIs, e.g. startContainer, stopContainer, getContainerStatus
force caller to pass in the NodeId as wells as the ContainerId.  Hence, caller has to maintain
both NodeId and ContainerId mapping on its own, which becomes a bit inconvenient sometimes.
> In fact, NMClient internally already cached the NodeId for the ContainerId, so the NodeId
in the API could be avoided.
