-------------------------------------
Summary: 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: Eugene Koifman
as of HIVE-11983, when a TransactionBatch is opened in StreamingAPI, a full
compliment of bucket files 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.
