Interface PartitionProducerStateChecker

All Known Implementing Classes:

RpcPartitionStateChecker

public interface PartitionProducerStateChecker

Intermediate partition state checker to query the JobManager about the state of the producer of a result partition.

These checks are triggered when a partition request is answered with a PartitionNotFound event. This usually happens when the producer of that partition has not registered itself with the network stack or terminated.

Method Summary

CompletableFuture<ExecutionState>	requestPartitionProducerState(org.apache.flink.api.common.JobID jobId, IntermediateDataSetID intermediateDataSetId, ResultPartitionID resultPartitionId) Requests the execution state of the execution producing a result partition.

Method Detail

requestPartitionProducerState

CompletableFuture<ExecutionState> requestPartitionProducerState(org.apache.flink.api.common.JobID jobId,
                                                                IntermediateDataSetID intermediateDataSetId,

Requests the execution state of the execution producing a result partition.

Parameters:

jobId - ID of the job the partition belongs to.

intermediateDataSetId - ID of the parent intermediate data set.

resultPartitionId - ID of the result partition to check. This identifies the producing execution and partition.

Returns:

Future holding the execution state of the producing execution.
