+## Setting up Zeppelin with Kerberos
+Logical setup with Zeppelin, Kerberos Distribution Center (KDC), and Spark on YARN:
+
+<img src="../assets/themes/zeppelin/img/docs-img/kdc_zeppelin.png">
+
+####Configuration Setup
+
+1. On the server that Zeppelin is installed, install Kerberos client modules and configuration,
krb5.conf.
+This is to make the server communicate with KDC.
+
+2. Set SPARK\_HOME in [ZEPPELIN\_HOME]/conf/zeppelin-env.sh to use spark-submit
+( Additionally, you might have to set “export HADOOP\_CONF\_DIR=/etc/hadoop/conf” )
+
+3. Add the two properties below to spark configuration ( [SPARK_HOME]/conf/spark-defaults.conf
):
+
+        spark.yarn.principal
+        spark.yarn.keytab
+
+  > **NOTE:** If you do not have access to the above spark-defaults.conf file, optionally,
you may add the lines to the Spark Interpreter through the Interpreter tab in the Zeppelin
UI.
+
+4. That's it. Play with Zeppelin !
