<![CDATA[NMTokenCache manages NMTokens required for an Application Master
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>
If running multiple Application Masters in the same JVM, a different cache
instance should be used for each Application Master.
<ul>
<li>
If using the {@link AMRMClient} and the {@link NMClient}, setting up
and using an instance cache is as follows:
<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:
<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:
<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} or
{@code NMClient}, or the async versions of them) with a protocol proxy
({@code ContainerManagementProtocolProxy} or
{@code ApplicationMasterProtocol}).]]>

The interface used by clients to submit a new reservation to the
{@code ResourceManager}.
</p>
<p>
The client packages all details of its request in a
{@link ReservationSubmissionRequest} object. This contains information
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
{@link ReservationDefinition}

<![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 extends AMRMClientAsync.AbstractCallbackHandler {
public void onContainersAllocated(List<Container> containers) {
[run tasks on the containers]
}
public void onContainersUpdated(List<Container> containers) {
[determine if resource allocation of containers have been increased in
the ResourceManager, and if so, inform the NodeManagers to increase the
resource monitor/enforcement on the containers]
}
public void onContainersCompleted(List<ContainerStatus> statuses) {
[update progress, check whether app is done]
}
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);
asyncClient.stop();
}
</pre>]]>
