----------------------------------------------
Summary: Factor cost of each SJ reduction when costing a follow-up
reduction
Key: HIVE-20775
URL: https://issues.apache.org/jira/browse/HIVE-20775
Project: Hive
Issue Type: Bug
Components: Physical Optimizer
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Currently, while costing the SJ in a plan, the stats of the a TS that is
reduced by a SJ are not adjusted after we have decided to keep a SJ in the
tree. Ideally, we could adjust the stats to take into account decisions that
have already been made.
