类 DefaultJobGraphStore<R extends ResourceVersion<R>>

java.lang.Object

org.apache.flink.runtime.jobmanager.DefaultJobGraphStore<R>

所有已实现的接口:

GloballyCleanableResource, LocallyCleanableResource, JobGraphStore, JobGraphStore.JobGraphListener, JobGraphWriter

public class DefaultJobGraphStore<R extends ResourceVersion<R>>
extends Object
implements JobGraphStore, JobGraphStore.JobGraphListener

Default implementation for JobGraphStore. Combined with different StateHandleStore, we could persist the job graphs to various distributed storage. Also combined with different JobGraphStoreWatcher, we could get all the changes on the job graph store and do the response.

构造器详细资料

DefaultJobGraphStore

public DefaultJobGraphStore(StateHandleStore<JobGraph,R> stateHandleStore,
                            JobGraphStoreWatcher jobGraphStoreWatcher,
                            JobGraphStoreUtil jobGraphStoreUtil)

方法详细资料

start

public void start(JobGraphStore.JobGraphListener jobGraphListener)
           throws Exception

从接口复制的说明: JobGraphStore

Starts the JobGraphStore service.

指定者:

start 在接口中 JobGraphStore

抛出:

Exception

stop

public void stop()
          throws Exception

从接口复制的说明: JobGraphStore

Stops the JobGraphStore service.

指定者:

stop 在接口中 JobGraphStore

抛出:

Exception

recoverJobGraph

@Nullable
public JobGraph recoverJobGraph(org.apache.flink.api.common.JobID jobId)
                                   throws Exception

从接口复制的说明: JobGraphStore

Returns the JobGraph with the given JobID or null if no job was registered.

指定者:

recoverJobGraph 在接口中 JobGraphStore

抛出:

Exception

putJobGraph

public void putJobGraph(JobGraph jobGraph)
                 throws Exception

从接口复制的说明: JobGraphWriter

Adds the JobGraph instance.

If a job graph with the same JobID exists, it is replaced.

指定者:

putJobGraph 在接口中 JobGraphWriter

抛出:

Exception

globalCleanupAsync

public CompletableFuture<Void> globalCleanupAsync(org.apache.flink.api.common.JobID jobId,
                                                  Executor executor)

从接口复制的说明: GloballyCleanableResource

globalCleanupAsync is expected to be called from the main thread. Heavy IO tasks should be outsourced into the passed cleanupExecutor. Thread-safety must be ensured.

指定者:

globalCleanupAsync 在接口中 GloballyCleanableResource

指定者:

globalCleanupAsync 在接口中 JobGraphWriter

参数:

jobId - The JobID of the job for which the local data should be cleaned up.

executor - The fallback executor for IO-heavy operations.

返回:

The cleanup result future.

localCleanupAsync

public CompletableFuture<Void> localCleanupAsync(org.apache.flink.api.common.JobID jobId,
                                                 Executor executor)

Releases the locks on the specified JobGraph.

Releasing the locks allows that another instance can delete the job from the JobGraphStore.

指定者:

localCleanupAsync 在接口中 LocallyCleanableResource

指定者:

localCleanupAsync 在接口中 JobGraphWriter

参数:

jobId - specifying the job to release the locks for

executor - the executor being used for the asynchronous execution of the local cleanup.

返回:

The cleanup result future.

getJobIds

public Collection<org.apache.flink.api.common.JobID> getJobIds()
                                                        throws Exception

从接口复制的说明: JobGraphStore

Get all job ids of submitted job graphs to the submitted job graph store.

指定者:

getJobIds 在接口中 JobGraphStore

返回:

Collection of submitted job ids

抛出:

Exception - if the operation fails

onAddedJobGraph

public void onAddedJobGraph(org.apache.flink.api.common.JobID jobId)

从接口复制的说明: JobGraphStore.JobGraphListener

Callback for JobGraph instances added by a different JobGraphStore instance.

Important: It is possible to get false positives and be notified about a job graph, which was added by this instance.

指定者:

onAddedJobGraph 在接口中 JobGraphStore.JobGraphListener

参数:

jobId - The JobID of the added job graph

onRemovedJobGraph

public void onRemovedJobGraph(org.apache.flink.api.common.JobID jobId)

从接口复制的说明: JobGraphStore.JobGraphListener

Callback for JobGraph instances removed by a different JobGraphStore instance.

指定者:

onRemovedJobGraph 在接口中 JobGraphStore.JobGraphListener

参数:

jobId - The JobID of the removed job graph
