SERDE backed schema for parquet storage in Hive

As of now, for a hive table stored as parquet, the schema can only be specified in Hive MetaStore. For our use-case, it is desired that the schema be provided by Thrift SerDe rather than MetaStore. Using thrift IDL as a schema provider, allows us to maintain a consistent schema across executions engines other than Hive such as Pig and Native MR.

Additionally, for a large sparse schema, it is much easier to build thrift objects, and use parquet-thrift/elephant-bird to convert them into columns/tuples rather than constructing the whole big tuple itself.

The issue names no files, tests, or entry points. Start by tracing how Hive MetaStore schemas and Thrift SerDes are handled, then review parquet-thrift and elephant-bird integration; done means a Hive parquet table can obtain its schema from Thrift IDL and remain usable across Hive, Pig, and Native MR.
