 ## Use `Shiro` to Configure Access to Zeppelin Interpreters in Enterprise Security Package (ESP) Clusters
 
 As noted above, the `%sh` interpreter isn't supported from HDInsight 4.0 onwards. Furthermore, since `%sh` interpreter introduces potential security issues, such as access keytabs using shell commands, it has been removed from HDInsight 3.6 ESP clusters as well. It means `%sh` interpreter isn't available when clicking **Create new note** or in the Interpreter UI by default.
