> Make Streaming API not create empty buckets (at least as an option)
> -------------------------------------------------------------------
>
> Key: HIVE-13403
> URL: https://issues.apache.org/jira/browse/HIVE-13403
> Project: Hive
> Issue Type: Bug
> Components: HCatalog, Transactions
> Affects Versions: 1.3.0
> Reporter: Eugene Koifman
> Assignee: Wei Zheng
> Priority: Critical
> Attachments: HIVE-13403.1.patch
>
>
> 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.
