Review comment:
Comment 7 -> add/alter/drop schema -> All these commands will not be
authorized for the users
Comment 8 -> PreAuthorizationCallEvent -> All PreAuthorizationCallEvent call
will not be authorized for the users.
Comment 2 to 6 -> all these needs changes to HiveMetastore to fire the auth
event and followed authorization changes. I shall address this in subsequent
JIRA once this patch is completed and validated. This needs a signification
change and verification for it.
Comment 1 -> CREATE CATALOG / ALTER CATALOG / DROP CATALOG can be done as
admin user which is already in place. Rest all users will not be authorized to
do these operations.
CREATE VIEW / ALTER VIEW / DROP VIEW - operations related to views will not
authorized for the users. Only admin users are allowed to do.

> Key: HIVE-21753

> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 3.1.2
> Reporter: Ramesh Mani
> Assignee: Ramesh Mani

>
> Currently HMS supports authorization using StorageBasedAuthorizationProvider
> which relies on permissions at filesystem – like HDFS. Hive supports a
> pluggable authorization interface, and multiple authorizer implementations
> (like SQLStd, Ranger, Sentry) are available to authorizer access in Hive.
> Extending HiveMetastore to use the same authorization interface as Hive will
> enable use of pluggable authorization implementations; and will result in
> consistent authorization across Hive, HMS and other services that use HMS
> (like Spark).
