类 DispatcherResourceCleanerFactory

java.lang.Object

org.apache.flink.runtime.dispatcher.cleanup.DispatcherResourceCleanerFactory

所有已实现的接口:

ResourceCleanerFactory

public class DispatcherResourceCleanerFactory
extends Object
implements ResourceCleanerFactory

DispatcherResourceCleanerFactory instantiates ResourceCleaner instances that clean cleanable resources from the Dispatcher.

We need to handle the JobManagerRunnerRegistry differently due to a dependency between closing the JobManagerRunner and the HighAvailabilityServices. This is fixed in FLINK-24038 using a feature flag to enable/disable single leader election for all the JobManager components. We can remove the priority cleanup logic after removing the per-component leader election.

方法详细资料

createLocalResourceCleaner

public ResourceCleaner createLocalResourceCleaner(org.apache.flink.runtime.concurrent.ComponentMainThreadExecutor mainThreadExecutor)

从接口复制的说明: ResourceCleanerFactory

Creates ResourceCleaner that initiates LocallyCleanableResource.localCleanupAsync(JobID, Executor) calls.

指定者:

createLocalResourceCleaner 在接口中 ResourceCleanerFactory

参数:

mainThreadExecutor - Used for validating that the LocallyCleanableResource.localCleanupAsync(JobID, Executor) is called from the main thread.

createGlobalResourceCleaner

public ResourceCleaner createGlobalResourceCleaner(org.apache.flink.runtime.concurrent.ComponentMainThreadExecutor mainThreadExecutor)

从接口复制的说明: ResourceCleanerFactory

Creates ResourceCleaner that initiates GloballyCleanableResource.globalCleanupAsync(JobID, Executor) calls.

指定者:

createGlobalResourceCleaner 在接口中 ResourceCleanerFactory

参数:

mainThreadExecutor - Used for validating that the GloballyCleanableResource.globalCleanupAsync(JobID, Executor) is called from the main thread.
