<1> if you did not specify default tablespace for a partition table. Then it's rely on

default tablespace settings of the schema. And then if you want to do a transportable-

tablespace migrate to the default tablespace . The TTS_check will return false.
So ,it's a very important option to specify default tablespace for a partition table.
<2> add a partition for a hash partioned table is very simple .
