------------------------------------------------

[~ashutoshc], would you mind taking a look at the new patch? :) The new patch addresses other
issues discovered while testing; I have updated the description of the issue to describe them.
Thanks!

> - Druid query type not recognized after Calcite upgrade; introduced by HIVE-13316.
> - Fix handling of NULL values for GroupBy queries.
> - Fix handling of dimension/metrics names, as those names in Druid are case sensitive.
> - Select Druid query to effectively return no rows when the result is empty (previously
returning a single row).
> - When it is split, each of the parts of a Select query might return more results than
threshold; set threshold to max integer in query so we do not face this problem.
