-------------------------------------
Summary: Long compilation time of complex query due to analysis
for materialized view rewrite
Key: HIVE-25941
URL: https://issues.apache.org/jira/browse/HIVE-25941
Project: Hive
Issue Type: Bug
Components: Materialized views
Reporter: Krisztian Kasa

When compiling query the optimizer tries to rewrite the query plan or subtrees
of the plan to use materialized view scans.
If

{code}
the compilation succeed in less then 10 sec otherwise it takes several minutes
(~ 5min) depending on the hardware.
