> One problem test case is: 
> create table intermediate(key int) partitioned by (p int) stored as orc;
> insert into table intermediate partition(p='455') select distinct key from src where
key >= 0 order by key desc limit 2;
> insert into table intermediate partition(p='456') select distinct key from src where
key is not null order by key asc limit 2;
> insert into table intermediate partition(p='457') select distinct key from src where
key >= 100 order by key asc limit 2;
> create table multi_partitioned (key int, key2 int) partitioned by (p int);
> from intermediate
> insert into table multi_partitioned partition(p=2) select p, key
> insert overwrite table multi_partitioned partition(p=1) select key, p;
