类 StopWithSavepointTerminationHandlerImpl

java.lang.Object

org.apache.flink.runtime.scheduler.stopwithsavepoint.StopWithSavepointTerminationHandlerImpl

所有已实现的接口:

StopWithSavepointTerminationHandler

public class StopWithSavepointTerminationHandlerImpl
extends Object
implements StopWithSavepointTerminationHandler

StopWithSavepointTerminationHandlerImpl implements StopWithSavepointTerminationHandler.

The operation only succeeds if both steps, the savepoint creation and the successful termination of the job, succeed. If the former step fails, the operation fails exceptionally without any further actions. If the latter one fails, a global fail-over is triggered before failing the operation.

The implementation expects the savepoint creation being completed before the executions terminate.

Returns the a CompletableFuture referring to the result of the stop-with-savepoint operation.

指定者:

getSavepointPath 在接口中 StopWithSavepointTerminationHandler

返回:

the CompletableFuture containing the path to the created savepoint in case of success.

handleSavepointCreation

参数:

completedSavepoint - the CompletedCheckpoint referring to the created savepoint

throwable - an error that was caught during savepoint creation
