I successfully built a 5 node cluster of HortonWorks HDP 2.2 using Ambari.
However I don't see Apache Spark in the installed services list.
I did some research and found that Ambari does not install certain components like hue etc. ( Spark was not in that list, but I guess its not installed).
How do I do a manual install of Apache spark on my 5 node HDP 2.2?
Or should I delete my cluster and perform a fresh install without using Ambari?
