Change subject: IMPALA-8797: Support database and table blacklist
......................................................................
IMPALA-8797: Support database and table blacklist
Add catalogd startup option for database and table blacklist. Blacklist
dbs/tables will be skipped in loading. Users won't see them when getting
database/table list, e.g. in SHOW DATABASES/TABLES. Dropping/creating
blacklist databases/tables/views are not allowed too.
Implementation:
Catalogd parses the --blacklist_dbs and --blacklist_tables options in
startup. Blacklist checks are added when loading the metadata, executing
DDL requests for create/drop.
Motivation:
By default, it's used to blacklist "sys" and "information_schema"
databases from Hive. Admin can use them to specify any databases/tables
that are not suitable for Impala to query.
Tests:
- Add java unit tests for blacklist related functions
- Add a custom cluster test: test_blacklist_dbs_and_tables.py
- Ran CORE tests
