HiveMetastore supports delegation token.
Does HiveServer2 support it as well? If not, do we have a plan for this?
Besides, on hive wiki
hive.server2.authentication - Authentication mode, default NONE. Options
are NONE, KERBEROS, LDAP and CUSTOM
Will HiveServer2 support PAM which could be configured to use multiple
authentication ways like OS, or LDAP as well?
