Masood Parvari commented on DRILL-2765:
---------------------------------------

[~sphillips] No Steven. I compiled myself that drill and that was a master branch drill. But
for reassurance I just again clone drill master branch (--branch master ) and it was pre compiled.
i just introduce jars dependencies by coping them from "jars" directory in 0.8.0 version to
the branch directory and I again run that example and again it throws a null pointer exception.
screen shot of commit-id screen is attached. I am really amazed how your query doesn't return
a null pointer exception. any clue please?
