------------------------------------------
Summary: Avoid loading Iceberg file metadata in Coordinator in
local catalog mode for metadata-only queries
Key: IMPALA-14823
URL: https://issues.apache.org/jira/browse/IMPALA-14823
Project: IMPALA
Issue Type: Bug
Reporter: Zoltán Borók-Nagy
DESCRIBE iceberg_table;
SHOW TABLE STATS iceberg_table;
Still fetches all metadata in the Coordinator from Catalogd. But for the above
queries they are not needed, so we shouldn't fetch them.
Some pointers in code:
