> The {{allocate()}} call is used in the {{YarnJobManager}} to send a heartbeat to the YARN resource manager. This call may block the JobManager actor system for arbitrary time, e.g. if retry handlers are set up within the call to allocate.
> I propose to use the {{AMRMClientAsync}}'s callback methods to send heartbeats and update the container information. The API is available for our supported Hadoop versions (2.3.0 and above).
