I read on the VLBD hive paper "Hive - A Warehousing Solution Over a
Map-Reduce    Framework"
that Partitions could have different schemas : (section 3.1 MetaStore) "
Partition - Each partition can have its own columns
and SerDe and storage information. This can be used
in the future to support schema evolution in a Hive
warehouse.
"

but the API:
http://hadoop.apache.org/hive/docs/r0.5.0/api/

only lists getSchema() for Table, and Partition does not have a
separate getSchema().

is the schema evolution feature really there?

Thanks
Yang
