------------------------------------
[~rmani] - Very thankful for commenting on GitHub! I am m44444 there. Just one
question if I could, seems like this PR will be released with 4.0.0, can this
patch be back ported to earlier versions in 2.x and 3.x? Thank you!

> 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).
