Thank you for the response. But the reference does not seem to be answering any
of those questions.

Hi,
Worth checking this link
Hello all,
I'm using Oozie to manage a Spark application on YARN cluster, in
yarn-cluster mode.
Recently I made some changes to the application in which the Hikari lib was
involved. Surprisingly when I started the job, I got ClassNotFound
exception for the Hikari classes. I'm passing a shade jar

Hi Mich.
This is a Spark user group mailing list where people can ask *any*
questions about spark.
You know SQL and streaming, but I don't think it's necessary to start a
replay with "*LOL*" to the question that's being asked.
No questions are to stupid to be asked.

First one
spark-sql> select 1 as `data.group` from abc group by data.group;
1
Time taken: 0.198 seconds, Fetched 1 row(s)
means that are assigning alias data.group to select and you are using that
alias -> data.group in your group by statement
This is equivalent to
spark-sql> select 1
