Does the function name is case sensitive in Hive?

What do you mean? There are no table valued functions in Hive.

@samelamin you have to make this dependent on the case sensitivity setting of the analyzer. This means you will have to turn this object into case class that takes a SQLConf as its argument.

ok cool thanks @hvanhovell ill amend it over the weekend. Do you know how I can run a specific set of tests on SBT?

@hvanhovell instead of creating a new case class, is there a way I can reuse the UnresolvedTableValuedFunction case class and just add in the SQLConf class?

Yeah, @gatorsmile is right. We don't do case sensitive resolution for functions. So you can ignore my comment, and undo the last change you have made.

So would you like me to revert the change to the case class?

Ok I can revert but how will we test it since the apply method isn't being called by the tests. They new up an unresolvedTableValuedFunction? Unless we hardcore it in unresolvedTableValuedFunction to always be case insensitive then I don't know how else to do it?

case Some(tvf) =>
val resolved = tvf.flatMap { case (argList, resolver) =>
argList.implicitCast(u.functionArgs) match {
