Description

• Install Ambari cluster with latest trunk bits
• Modify /var/lib/ambari-server/resources/common-services/ZEPPELIN/0.6.0.2.5/metainfo.xml to add the following:

  Add to <dependencies> node of ZEPPELIN_MASTER:
              <dependency>
                <name>SPARK/LIVY_SERVER</name>
                <scope>host</scope>
              </dependency>
  Add to <service> node:
        <requiredServices>
          <service>SPARK</service>
        </requiredServices>
  

• Install HDP 2.5.3 cluster with Spark
• Once the cluster is installed, use Add Service Wizard to add Zeppelin
• Assign Slaves and Clients step should appear (without the metainfo.xml change, it will be skipped)
• The user should not be able to proceed beyond this page unless at least one Livy Server is selected <- this validation should be handled by the stack advisor
