When you use the default Serde (lazySerde) and sequence files hive writes a
SequenceFile(create table x .... stored as sequence file) , the key is null
and hive serializes all the columns into a Text Writable that is easy for
other tools to read. Hive does not dictate the input format or the output
format, usually you can get hive to produce exactly what you want by mixing
and matching serde and output format options.
