Add some unit test in order to test :

 - HiveSerDe : fix some bugs about long and byte datas
 - DeprecatedParquetInputFormat : add StatsSerDe method
 - MapWritableWriter : fix bug if we start and close without adding values
 - UtilitiesTestMethods : almost everything is from parquet-pig. Very useful
 - TestDeprecated{Input,Output}Format : in order to test the hive stuff

Update pom.xml :

 - Hive-* 0.10 version
 - Add column for test purpose
