> Partitions are not pruned when joined on the partition columns.
> This is the same issue as HIVE-9152.
> Ex: 
> Select .... from tab where partcol=1 will prune on value 1
> Select .... from tab join dim on (dim.partcol=tab.partcol) where 
> dim.partcol=1 will scan all partitions.
> Tables are based on parquets.
