----------------------------------------------
Summary: Avoid expensive call to removeAll in DefaultGraphWalker
Key: HIVE-11652
URL: https://issues.apache.org/jira/browse/HIVE-11652
Project: Hive
Issue Type: Bug
Components: Logical Optimizer, Physical Optimizer
Affects Versions: 1.3.0, 2.0.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
When the plan is too large, the removeAll call in DefaultGraphWalker (line 140)
will take very long as it will have to go through the list looking for each of
the nodes. We try to get rid of this call by rewriting the logic in the walker.
