The CSVSerde is available in Hive 0.14 and greater.
The CSV SerDe is based from https://github.com/ogrodnek/csv-serde, and was added to the Hive distribution in HIVE-7777.
This SerDe works for most CSV data, but does not handle embedded newlines. To use the SerDe, specify the fully qualified class name org.apache.hadoop.hive.serde2.OpenCSVSerde.
Documentation is based on original documentation at https://github.com/ogrodnek/csv-serde.
