------------------------------
Summary: If a query has been optimized by correlation optimizer,
join auto convert cannot optimize it
Key: HIVE-3671
URL: https://issues.apache.org/jira/browse/HIVE-3671
Project: Hive
Issue Type: Sub-task
Components: Query Processor
Reporter: Yin Huai
Assignee: Yin Huai
Currently, if a query has been optimized by correlation optimizer, the first
operator at the reduce side will be CorrelationReducerDispatchOperator. Since
CommonJoinResolver will only work if the first operator at the reduce side is a
join operator, join auto convert cannot optimize this query. This jira is used
to discuss how to make correlation optimizer compatible with join auto convert.
