------------------------------
Attachment: HIVE-4342.D10407.1.patch

ALL with nested JOIN and UNION ALL".
Reviewers: JIRA
HIVE-4342 temp
UNION ALL query with JOIN in first part and another UNION ALL in second part
gives NPE.
JOIN
UNION ALL
UNION ALL
Attachments:
1. HiveCommands.txt : command script to setup schema for query under
consideration.
2. sourceData1.txt and sourceData2.txt : required for above command script.
3. Query.txt : Exact query which produces NPE.
NOTE: you will need to update path to sourceData1.txt and sourceData2.txt in
the HiveCommands.txt to suit your environment.
Attached files contain the schema and exact query which fails on Hive 0.9.
It is worthwhile to note that the same query executes successfully on Hive 0.7.
