HIVE-4142 [jira] Remove inferring partition specification behavior
(Harish Butani via Ashutosh Chauhan)

Summary:
remove behavior that infers partitioning

Remove behavior that:

	implicitly sets the partition specification of a UDAF

this interferes with:

	the user wanting to apply a UDAF on the entire dataset
	is ambiguous once we support multiple partitions in 1 query.

Test Plan: updated tests
