> Right now, we choose to use partition lever metadata. All metadata (column names, column
types, fileformat, serde class, serde properties) right now are from partition level metadata.
But hive does not support a method now to alter all existing partitions' metadata, so users
mostly choose to alter table metadata, and think hive will use the new  table level metadata.

> One approach is that we may need to provide a way to let user alter all partitions' metadata
with one simple command. Right now a short term solution is to only get fileformat, serde
class metadata from paritition level metadata, and use all other metadata from table.
> any comments?
