Interface PartitionProducerStateChecker

All Known Implementing Classes:

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.
