    <![CDATA[Object to represent a single container request for resources. Scheduler
 documentation should be consulted for the specifics of how the parameters
 are honored.

 By default, YARN schedulers try to allocate containers at the requested
 locations but they may relax the constraints in order to expedite meeting
 allocations limits. They first relax the constraint to the same rack as the
 requested node and then to anywhere in the cluster. The relaxLocality flag
 may be used to disable locality relaxation and request containers at only
 specific locations. The following conditions apply.
 <ul>
 <li>Within a priority, all container requests must have the same value for
 locality relaxation. Either enabled or disabled.</li>
 <li>If locality relaxation is disabled, then across requests, locations at
 different network levels may not be specified. E.g. its invalid to make a
 request for a specific node and another request for a specific rack.</li>
 <li>If locality relaxation is disabled, then only within the same request,
 a node and its rack may be specified together. This allows for a specific
 rack with a preference for a specific node within that rack.</li>
 <li></li>
 </ul>
 To re-enable locality relaxation at a given priority, all pending requests
 with locality relaxation disabled must be first removed. Then they can be
 added back with locality relaxation enabled.

 All getters return immutable values.]]>

 communicating with individual NodeManagers.
 <p/>
 By default Yarn client libraries {@link AMRMClient} and {@link NMClient} use
 {@link #getSingleton()} instance of the cache.
 <ul>
 <li>Using the singleton instance of the cache is appropriate when running a
 single ApplicationMaster in the same JVM.</li>
 <li>When using the singleton, users don't need to do anything special,
 {@link AMRMClient} and {@link NMClient} are already set up to use the default
 singleton {@link NMTokenCache}</li>
 </ul>
 <p/>
 If running multiple Application Masters in the same JVM, a different cache
 instance should be used for each Application Master.
 <p/>
 <ul>
 <li>
 If using the {@link AMRMClient} and the {@link NMClient}, setting up and using
 an instance cache is as follows:
 <p/>

 <pre>
   NMTokenCache nmTokenCache = new NMTokenCache();
   AMRMClient rmClient = AMRMClient.createAMRMClient();
   NMClient nmClient = NMClient.createNMClient();
   nmClient.setNMTokenCache(nmTokenCache);
   ...
 </pre>
 </li>
 <li>
 If using the {@link AMRMClientAsync} and the {@link NMClientAsync}, setting up
 and using an instance cache is as follows:
 <p/>

 <pre>
   NMTokenCache nmTokenCache = new NMTokenCache();
   AMRMClient rmClient = AMRMClient.createAMRMClient();
   NMClient nmClient = NMClient.createNMClient();
   nmClient.setNMTokenCache(nmTokenCache);
   AMRMClientAsync rmClientAsync = new AMRMClientAsync(rmClient, 1000, [AMRM_CALLBACK]);
   NMClientAsync nmClientAsync = new NMClientAsync("nmClient", nmClient, [NM_CALLBACK]);
   ...
 </pre>
 </li>
 <li>
 If using {@link ApplicationMasterProtocol} and
 {@link ContainerManagementProtocol} directly, setting up and using an
 instance cache is as follows:
 <p/>

 <pre>
   NMTokenCache nmTokenCache = new NMTokenCache();
   ...
   ApplicationMasterProtocol amPro = ClientRMProxy.createRMProxy(conf, ApplicationMasterProtocol.class);
   ...
   AllocateRequest allocateRequest = ...
   ...
   AllocateResponse allocateResponse = rmClient.allocate(allocateRequest);
   for (NMToken token : allocateResponse.getNMTokens()) {
     nmTokenCache.setToken(token.getNodeId().toString(), token.getToken());
   }
   ...
   ContainerManagementProtocolProxy nmPro = ContainerManagementProtocolProxy(conf, nmTokenCache);
   ...
   nmPro.startContainer(container, containerContext);
   ...
 </pre>
 </li>
 </ul>
 It is also possible to mix the usage of a client (<code>AMRMClient</code> or
 <code>NMClient</code>, or the async versions of them) with a protocol proxy (
 <code>ContainerManagementProtocolProxy</code> or
 <code>ApplicationMasterProtocol</code>).]]>

 about the amount of capacity, temporal constraints, and gang needs.
 Furthermore, the reservation might be composed of multiple stages, with
 ordering dependencies among them.
 </p>

 <p>
 In order to respond, a new admission control component in the
 {@code ResourceManager} performs an analysis of the resources that have
 been committed over the period of time the user is requesting, verify that
 the user requests can be fulfilled, and that it respect a sharing policy
 (e.g., {@code CapacityOverTimePolicy}). Once it has positively determined
 that the ReservationRequest is satisfiable the {@code ResourceManager}
 answers with a {@link ReservationSubmissionResponse} that includes a
 {@link ReservationId}. Upon failure to find a valid allocation the response
 is an exception with the message detailing the reason of failure.
 </p>

 <p>
 The semantics guarantees that the {@link ReservationId} returned,
 corresponds to a valid reservation existing in the time-range request by
 the user. The amount of capacity dedicated to such reservation can vary
 overtime, depending of the allocation that has been determined. But it is
 guaranteed to satisfy all the constraint expressed by the user in the

    <![CDATA[<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>

 <pre>
 {@code
 AMRMClientAsync asyncClient =
     createAMRMClientAsync(appAttId, 1000, new MyCallbackhandler());
 asyncClient.init(conf);

    <![CDATA[<code>NMClientAsync</code> handles communication with all the NodeManagers

 maintains a thread pool to communicate with individual NMs where a number of
 worker threads process requests to NMs by using {@link NMClientImpl}. The max

 {@link YarnConfiguration#NM_CLIENT_ASYNC_THREAD_POOL_MAX_SIZE}.

 It should be used in conjunction with a CallbackHandler. For example

 <pre>
 {@code

 The callback interface needs to be implemented by {@link NMClientAsync}
 users. The APIs are called when responses from <code>NodeManager</code> are
 available.
 </p>

 <p>
 Once a callback happens, the users can chose to act on it in blocking or
 non-blocking manner. If the action on callback is done in a blocking
 manner, some of the threads performing requests on NodeManagers may get
 blocked depending on how many threads in the pool are busy.
 </p>

 <p>
 The implementation of the callback function should not throw the
 unexpected exception. Otherwise, {@link NMClientAsync} will just
 catch, log and then ignore it.
