void endInput()
       throws Exception

It is notified that no more data will arrive from the input.

WARNING: It is not safe to use this method to commit any transactions or other side effects! You can use this method to flush any buffered data that can later on be committed e.g. in a CheckpointListener.notifyCheckpointComplete(long).

NOTE: Given it is semantically very similar to the StreamOperator.finish() method. It might be dropped in favour of the other method at some point in time.
