This is great news sir. It shows perseverance pays at last.
Can you inform us when the write-up is ready so I can set it up as well please.
I know a bit about the advantages of having Hive using Spark engine. However,
the general question I have is when one should use Hive on spark as opposed to
Hive on MapReduce engine?
Thanks again
