/**
* <code>AMRMClientAsync</code> handles communication with the ResourceManager
* and provides asynchronous updates on events such as container allocations and
* completions. It contains a thread that sends periodic heartbeats to the
* ResourceManager.
*
* It should be used by implementing a CallbackHandler:
* <pre>
* {@code
* class MyCallbackHandler implements AMRMClientAsync.CallbackHandler {
* public void onContainersAllocated(List<Container> containers) {
* [run tasks on the containers]
* }
*

* }
*
* public void onNodesUpdated(List<NodeReport> updated) {}
*
* public void onReboot() {}
* }
* }
* </pre>
*
* The client's lifecycle should be managed similarly to the following:
*
* <pre>
* {@code
* AMRMClientAsync asyncClient =
* createAMRMClientAsync(appAttId, 1000, new MyCallbackhandler());
* asyncClient.init(conf);
* asyncClient.start();
* RegisterApplicationMasterResponse response = asyncClient
* .registerApplicationMaster(appMasterHostname, appMasterRpcPort,
* appMasterTrackingUrl);
* asyncClient.addContainerRequest(containerRequest);
* [... wait for application to complete]
* asyncClient.unregisterApplicationMaster(status, appMsg, trackingUrl);
