Na Li updated SENTRY-2540:
--------------------------
Description:
When there are thousands of databases, SHOW DATABASES may take a really long
time because SENTRY checks if user has any of the following privileges on that
database for filtering out the database
DBModelAction.SELECT, DBModelAction.INSERT, DBModelAction.ALTER,
DBModelAction.CREATE, DBModelAction.DROP, DBModelAction.INDEX,
DBModelAction.LOCK
To speedup the authorization checking for this case, Sentry can check only the
select privilege for SHOW DATABASES and SHOW TABLES based on configuration.
