GitHub user tgrall opened a pull request:

Add the _id when using a * projection see JIRA : DRILL-3505
When the user is doing STAR_COLUMN , the system now asks mongodb to return
the _id.
Behing the scene the mongo query does not have any field in the
projection, so it returns all fields including the _id.
I was not able to run succesfully any test in the current branch so I could
not add test. (will ask question on ml)
