---------------------------------------
Summary: verify SMB join with multiple inserts
Key: HIVE-17675
URL: https://issues.apache.org/jira/browse/HIVE-17675
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Hive has a family of joins that interact with sorted and bucketed tables. Afaik
one (all?) of them actually rely on the table being sorted, rather than sorting
it.
If one runs insert on such a table without merge more than once, there'd be 2+
files for every bucket that are individually sorted; but globally, the table
would no longer be sorted.
Would these joins work/disable themselves correctly in this case, or could it
produce incorrect results? We might need a q file.
