> 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?
