>
> as of HIVE-11983, when a TransactionBatch is opened in StreamingAPI, a full compliment of bucket files (AbstractRecordWriter.createRecordUpdaters()) is created on disk even though some may end up receiving no data.
> It would be better to create them on demand and not clog the FS.
> Tez can handle missing (empty) buckets and on MR bucket join algorithms will check if all buckets are there and bail out if not.
