What is the benefit of using CDH over other Distributors

Question

Why do many people use CDH instead of using Apache-Hadoop or Apache-Spark etc. solely?

What are it's advantages?

If I want to use Apache-Spark for data analysis, is it better to use CDH or Apache-Spark Framework Solely?

Answer 1

CDH is basically a packaged deal, where you have a good interface with everything installed in it.

Spark Version may be 1.6 now, but it might be upgraded later.

If you want to work on spark, its better you install hadoop and spark separately in your VM or System. That'll be enough. You can add other frameworks later when needed.
