Method Detail

putJobGraph

void putJobGraph(JobGraph jobGraph)
          throws Exception

Adds the JobGraph instance.

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

Throws:

Exception

putJobResourceRequirements

void putJobResourceRequirements(org.apache.flink.api.common.JobID jobId,
                                JobResourceRequirements jobResourceRequirements)
                         throws Exception

Persist job resource requirements for the given job.

Parameters:

jobId - job the given requirements belong to

jobResourceRequirements - requirements to persist

Throws:

Exception - in case we're not able to persist the requirements for some reason

localCleanupAsync

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

Description copied from interface: 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.

Specified by:

localCleanupAsync in interface LocallyCleanableResource

Parameters:

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

executor - The fallback executor for IO-heavy operations.

Returns:

The cleanup result future.

globalCleanupAsync

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

Description copied from interface: 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.

Specified by:

globalCleanupAsync in interface GloballyCleanableResource

Parameters:

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

executor - The fallback executor for IO-heavy operations.

Returns:

The cleanup result future.
