Committer for StreamingFileWriter. This is the single (non-parallel) task. It collects all the partition information sent from upstream, and triggers the partition submission decision when it judges to collect the partitions from all tasks of a checkpoint.

Processing steps: 1.Partitions are sent from upstream. Add partition to trigger. 2.TaskTracker say it have already received partition data from all tasks in a checkpoint. 3.Extracting committable partitions from PartitionCommitTrigger. 4.Using PartitionCommitPolicy chain to commit partitions.

See StreamingFileWriter.notifyCheckpointComplete(long).
