------------------------------------------
Summary: Add tests for EXPLAIN FORMATTED CBO on TPC-DS queries
Key: HIVE-29360
URL: https://issues.apache.org/jira/browse/HIVE-29360
Project: Hive
Issue Type: Test
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
The {{EXPLAIN FORMATTED}} CBO command returns the CBO plan serialized as JSON,
which is a format that can be easily consumed and processed by other
applications. Currently we don't have a lot of coverage especially around the
CBO part.

$ grep -Ri "explain.*formatted" ql/src/test/queries/ | wc -l

The goal is to add tests with {{EXPLAIN FORMATTED CBO}} for all TPC-DS queries
to improve coverage around this feature and guard against regressions.
