Hi [~alangates] Sorry for not getting back to you in time. I noticed that the {{getTokenStore}}
method in {{MetastoreDelegationTokenManager}} class will not work for {{DBTokenStore}} and
{{ZKTokenStore}} since they implement {{org.apache.hadoop.hive.thrift.DelegationTokenStore}}
instead of {{org.apache.hadoop.hive.metastore.security.DelegationTokenStore}}. Is this intentional?
How do you propose users to handle this? Should we move the these two tokenStores to standalone-metastore
package too?

> As part of moving the metastore into a standalone package, it will no longer have access
to the shims.  This means we need to either copy them or access the underlying Hadoop operations
directly.
