flink git commit: [FLINK-4456] Replace Akka specific types by
interfaces in Task
Repository: flink
Updated Branches:
refs/heads/master 02b852e35 -> 0735b5b93
[FLINK-4456] Replace Akka specific types by interfaces in Task
Introduce TaskExecutionStateListener for Task
Replace JobManagerGateway in Task by InputSplitProvider and CheckpointNotifier
Replace the TaskManager ActorGateway by TaskManagerConnection in Task
Rename taskmanager.CheckpointNotifier into CheckpointResponder; rename TaskExecutionStateListener.notifyTaskExecutionState into notifyTaskExecutionStateChanged
Remove InputSplitProvider.start; add ClassLoader parameter to InputSplitProvider.getNextInputSplit
Removes the unused class InputSplitIterator.
Update InputSplitProvider JavaDocs
This closes #2456.
