Hadoop chokes on SQL because its not relational.
You talk about 'world class' SQL engines, which they don't have. World Class was Informix XPS which supposedly was moved in to their IDS product. But you don't use a distributed database for OLTP.
Hint: Try holding a distributed lock.
Big Data isn't relational. Do you not remember Stonebraker's rant when Google released their papers? It was classic.
Spark is spark. There are good things and bad things about Spark. And if you're in the Spark camp, that means you're not a big fan of Flink. (There are some of us who are neutral and work with both and understand the merits of both. )
Again, I have to post Anon. Too many people in this space know who I am, and some even know my alias that I use here.
