> HDFSCompressedDataStream currently uses flush() to flush the compressed streams. Unfortunately, in at least Snappy and GZip, those operations are no-ops. So we have to go back to using finish() in order to ensure the durability of writes at Transaction boundaries.
> In addition to finish(), resetState() must be called.
