-------------------------------------
[~nandakumar131] Thanks for the comments. I completely agree with your comment.
bq. default asynchronous and we can make XceiverClient#sendCommand call into
XceiverClient#sendCommandAsync(request).get() which will
I would like to do that in some later patch since if I do that now, I have to
make corresponding changes in ContainerProtocolCalls, which will make this
patch larger and we will we have to rework changes in ContainerProtocolCalls
later. My aim was to illustrate the idea of making the async patch first class,
we need a series of patches on top of this to get all the way to Corona. So I
took the path of leaving the signatures as-is for time being.

> This is an umbrella JIRA that needs to support a set of APIs in Asynchronous
> form.
> For containers -- or the datanode API currently supports a call
> {{sendCommand}}. we need to build proper programming interface and support an
> async interface.
> There is also a set of SCM API that clients can call, it would be nice to
> support Async interface for those too.
