Overall I think this is better, thanks! One minor issue is that hive-thriftserver is missing from the SQL tests (Sorry, I think I left this out when you asked).

Only SQL files have been modified
SQL and non-SQL files have been modified
Only non-SQL files have been modified

• 1. looks good to me
• 2. runs all tests, hive is included
• 3. runs all tests, hive is not included

Is there a reason for the difference in the 2 & 3? I think its okay to only run hive tests when catalyst, sql, or infrastructure (scripts, build files, etc) changes. Though I'll let others chime in here too.

No problem. Just give me an updated list of arguments to pass to sbt when you just want to test SQL components, and I'll submit a new PR to fix that.

I'm not sure; I believe this was the behavior from before my patch.

Just add hive-thriftserver/test to the sbt command for SQL.

Sorry, I think I'm confused and this is actually correct as is.

Done in #2442.
