    Description

      Follow-up on HIVE-640. We should use LazyBinarySerDe in several places in the code to improve the efficiency: value between map-reduce boundary, temporary tables.
      We should also allow users to create tables stored as binary format.

      CREATE TABLE xxx (...)
ROW FORMAT BINARY
STORED AS SEQUENCEFILE;
