> How should this work?  Should it work like Insert Overwrite T select * from T 
> where 1=2?
> This should create a new empty base_x/ and thus operate w/o violating 
> Snapshot Isolation semantics.
> This makes sense for specific partition or unpartitioned table.  What about 
> "Truncate T" where T is partitioned?  Is the expectation to wipe out all 
> partition info or to make each partition empty?
