+<h5>Secure RPC client - Thrift<a class="headerlink" href="#secure-rpc-client-thrift"
title="Permalink to this headline">¶</a></h5>
+<p>As of Flume 1.6.0, Thrift source and sink supports kerberos based authentication.
+The client needs to use the getThriftInstance method of <tt class="docutils literal"><span
class="pre">SecureRpcClientFactory</span></tt>
+to get hold of a <tt class="docutils literal"><span class="pre">SecureThriftRpcClient</span></tt>.
<tt class="docutils literal"><span class="pre">SecureThriftRpcClient</span></tt>
extends
+<tt class="docutils literal"><span class="pre">ThriftRpcClient</span></tt>
which implements the <tt class="docutils literal"><span class="pre">RpcClient</span></tt>
interface. The kerberos
+authentication module resides in flume-ng-auth module which is
+required in classpath, when using the <tt class="docutils literal"><span class="pre">SecureRpcClientFactory</span></tt>.
Both the client
+principal and the client keytab should be passed in as parameters through the
+properties and they reflect the credentials of the client to authenticate
+against the kerberos KDC. In addition, the server principal of the destination
+Thrift source to which this client is connecting to, should also be provided.
+The following example shows how to use the <tt class="docutils literal"><span class="pre">SecureRpcClientFactory</span></tt>
+within a user&#8217;s data-generating application:</p>
