   > @jcamachor @zabetak I was thinking of changing all the existing tpcds 
queries to replace literals with `?` and run explain on tpcds queries (using 
TestTezPerfCliDriver). This should provide us with some good test coverage. 
What I am undecided on is if it worth pushing it to hive repo and have a 
separate clidriver testing execute/prepare for tpcds. What do you suggest?
   
   If we want to avoid regressions I guess having the queries in the repo makes 
sense. Apart from that I guess that not all of the tpcds queries are needed to 
ensure code coverage. Possibly after testing you will end-up with a subset that 
is sufficient.
