> * 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:
> {noformat}
> 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>
> {noformat}
> * 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
