Rajesh Balamohan created HIVE-27183:
---------------------------------------
Summary: Iceberg: Table information is loaded multiple times
Key: HIVE-27183
URL: https://issues.apache.org/jira/browse/HIVE-27183
Project: Hive
Issue Type: Improvement
Reporter: Rajesh Balamohan
HMS::getTable invokes "HiveIcebergMetaHook::postGetTable" which internally
loads iceberg table again.
If this isn't needed or needed only for show-create-table, do not load the
table again.
