----------------------------------

Does it make sense to print some log every so often to let users now, if the
application is stuck in new/saving state for a long time? Say every 10-15 times
of the polling-interval ?

YarnClient.getApplicationReport has opened the door for querying application
states.If the client is blocked by YarnClient.submitApplication for a long
time, I think the client can use YarnClient.getApplicationReport to query the
state. Then, it can decide whether it want to terminate the submission or
something. IMHO, it's the client's business.

> Currently, when submitting an application, storeApplication will be called
> for recovery. However, it is a blocking API, and is likely to block
> concurrent application submissions. Therefore, it is good to make application
> submission asynchronous, and postpone storeApplication.
