---------------------------------------
Summary: Table details are retrieved twice during query
compilation phase
Key: HIVE-22789
URL: https://issues.apache.org/jira/browse/HIVE-22789
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Reporter: Rajesh Balamohan
https://issues.apache.org/jira/browse/HIVE-22366 takes care of normalizing
table details so that {{tabNameToTabObject}} is effectively used in
CalcitePlanner.
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/parse/CalcitePlanner.java#L513
effectively invalidates entire {{tabNameToTabObject}} cache and forces to
recompute the details. It would be good to check whether this can be avoided.
