<![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>).]]>

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 implements AMRMClientAsync.CallbackHandler {
|
|
public void onContainersAllocated(List<Container> containers) {
|
|
[run tasks 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();
|
|
}

<![CDATA[<code>NMClientAsync</code> handles communication with all the NodeManagers
|
|
and provides asynchronous updates on getting responses from them. It
|
|
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
|
|
size of the thread pool is configurable through
|
|
{@link YarnConfiguration#NM_CLIENT_ASYNC_THREAD_POOL_MAX_SIZE}.
|
|
|
|
It should be used in conjunction with a CallbackHandler. For example
|
|
|
|
<pre>
|
|
{@code
|
|
class MyCallbackHandler implements NMClientAsync.CallbackHandler {
|
|

|
|
|
public void onContainerStatusReceived(ContainerId containerId,
|
|
ContainerStatus containerStatus) {
|
|
[make use of the status of the container]
|
|
}
|
|
|
|
public void onContainerStopped(ContainerId containerId) {

public void onStartContainerError(

|

}
|
|
|
|
public void onStopContainerError(

ContainerId containerId, Throwable t) {

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.
