方法概要

限定符和类型	方法和说明
default CompletableFuture<Void>	globalCleanupAsync(org.apache.flink.api.common.JobID jobId, Executor executor) globalCleanupAsync is expected to be called from the main thread.

void	putJobGraph(JobGraph jobGraph) Adds the JobGraph instance.

方法详细资料

putJobGraph

void putJobGraph(JobGraph jobGraph)
          throws Exception

Adds the JobGraph instance.

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

抛出:

Exception

localCleanupAsync

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

从接口复制的说明: LocallyCleanableResource

localCleanupAsync 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:

localCleanupAsync 在接口中 LocallyCleanableResource

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.

globalCleanupAsync

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

从接口复制的说明: GloballyCleanableResource

指定者:

globalCleanupAsync 在接口中 GloballyCleanableResource

参数:

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