Now that BEAM-1074 is resolved a user can improve parallelism simply by setting 
the {{spark.default.parallelism}} configuration.
[~amitsela] I believe we can close this ticket.

Agree. closed as invalid.
If use cases prove the need, we can consider a "repartition" to max parallelism 
(or a pre-set one) post read.
