> Both Table and Partition are just wrappers of the thrift class TTable and TPartition.
> However, Table and Partition are not serializable, and there are no guarantee in the code to make sure Table is in sync with the field of TTable.
> We should make Table and Partition serializable by only serializing the TTable and TPartition fields, and we should hide the TTable details inside the Table class.
