Description
Currently some Thrift objects like THdfsPartition are used both in the context of descriptors (i.e sent to the backend) and in the context of catalog objects (sent from the catalogd to impalad). The Thrift struct definition doesn't really clarify which fields are used where, and in fact the frontend currently fills in some fields in the Descriptor which are not actually read by the backend. We should more clearly document which fields are necessary where, and only serialize those that are necessary.
