Kyuubi extends the use of STS in a multi-tenant model based on a unified
interface and relies on the concept of multi-tenancy to interact with cluster
managers to finally gain the ability of resources sharing/isolation and data
security. The loosely coupled architecture of the Kyuubi server and engine
dramatically improves the client concurrency and service stability of the

-Authentication
---------------
+Kerberos Authentication
+-----------------------
+Since 1.6.0, Kyuubi JDBC driver implements the Kerberos authentication based
on JAAS framework instead of `Hadoop UserGroupInformation`_,
+which means it does not forcibly rely on Hadoop dependencies to connect a
kerberized Kyuubi Server.
+Kyuubi JDBC driver supports different approaches to connect a kerberized
Kyuubi Server. First of all, please follow
+the `krb5.conf instruction`_ to setup ``krb5.conf`` properly.

+Authentication by Principal and Keytab
+**************************************
+
+.. versionadded:: 1.6.0
+
+.. tip::
+
+ It's the simplest way w/ minimal setup requirements for Kerberos
authentication.
+
+It's straightforward to use principal and keytab for Kerberos authentication,
just simply configure them in the JDBC URL.
+
+.. code-block::
+ jdbc:subprotocol://<zookeeper
quorum>/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=kyuubi
+
jdbc:kyuubi://host:port/schema;clientKeytab=<clientKeytab>;clientPrincipal=<clientPrincipal>;serverPrincipal=<serverPrincipal>
+
+- clientKeytab: path of Kerberos ``keytab`` file for client authentication
+- clientPrincipal: Kerberos ``principal`` for client authentication
+- serverPrincipal: Kerberos ``principal`` configured by
`kyuubi.kinit.principal` at the server side. ``serverPrincipal`` is available
+ since 1.7.0, for previous versions, use ``principal`` instead.
+
+Authentication by Principal and TGT Cache
+*****************************************
+
+Another typical usage of Kerberos authentication is using `kinit` to generate
the TGT cache first, then the application
+does Kerberos authentication through the TGT cache.
+
+.. code-block::
+
+ jdbc:kyuubi://host:port/schema;serverPrincipal=<serverPrincipal>
+
+Authentication by `Hadoop UserGroupInformation`_ ``doAs`` (programing only)
+***************************************************************************
+
+.. tip::
+
+ This approach allows project which already uses `Hadoop
UserGroupInformation`_ for Kerberos authentication to easily
+ connect the kerberized Kyuubi Server. This approach does not work between
[1.6.0, 1.7.0], and got fixed in 1.7.1.
+
+.. code-block::
+
+ String jdbcUrl =
"jdbc:kyuubi://host:port/schema;serverPrincipal=<serverPrincipal>"
+ UserGroupInformation ugi =
UserGroupInformation.loginUserFromKeytab(clientPrincipal, clientKeytab);
+ ugi.doAs((PrivilegedExceptionAction<String>) () -> {
+ Connection conn = DriverManager.getConnection(jdbcUrl);
