Install the JCE
  1. On the Ambari Server, obtain the JCE policy file appropriate for the JDK version in your cluster.

    For example:

    wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jce/8/jce_policy-8.zip"
    
  2. Save the policy file archive in a temporary location.

  3. On Ambari Server and on each host in the cluster, add the unlimited security policy JCE jars to $JAVA_HOME/jre/lib/security/.

    For example, run the following to extract the policy jars into the JDK installed on your host:

    unzip -o -j -q jce_policy-8.zip -d /usr/jdk64/jdk1.8.0_40/jre/lib/security/

  4. Restart Ambari Server: sudo ambari-server restart

  5. Proceed to Running the Security Wizard.
