You сan specify INPUTFORMAT, OUTPUTFORMAT, SERDE in STORED AS when creating table. Hive allows you to separate your record format from your file format. You can provide custom classes for INPUTFORMAT, OUTPUTFORMAT, SERDE. See details: http://www.dummies.com/programming/big-data/hadoop/defining-table-record-formats-in-hive/

Alternatively you can write simply STORED AS ORC or STORED AS TEXTFILE for example. STORED AS ORC statement already takes care about INPUTFORMAT, OUTPUTFORMAT and SERDE. This allows you not to write those long fully qualified Java class names for INPUTFORMAT, OUTPUTFORMAT, SERDE. Just STORED AS ORC instead.
