---------------------------------
Summary: UNION ALL query fails "while setting up Foreman"
Key: DRILL-1395
URL: https://issues.apache.org/jira/browse/DRILL-1395
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 0.5.0
Reporter: Bob Rumsby
The two sides of the UNION are not equivalent because one of the files has an
additional column, but Aman tells me that this should work in a schema-less
environment anyway. (I was expecting it to fail but with a more meaningful
error because I am used to relational database UNION queries where a
corresponding number of columns is expected on either side of the UNION
operator.)
The query fails whether or not the LIMIT is applied. EXPLAIN for this query
also fails.
0: jdbc:drill:> select * from `clicks/clicks.campaign.json` union all select *
from `clicks/clicks.json` limit 5;
Query failed: Failure while setting up Foreman. DrillUnionRel#23471

Error: exception while executing query: Failure while trying to get next result
