HiveJsonSerDe
The native Hive / HCatalog JsonSerDe. Used by Firehose for deserializing data, which means converting it from the JSON format in preparation for serializing it to the Parquet or ORC format. This is one of two deserializers you can choose, depending on which one offers the functionality you need. The other option is the OpenX SerDe.

Properties
Indicates how you want Firehose to parse the date and timestamps that may be present in your input data JSON. To specify these format strings, follow the pattern syntax of JodaTime's DateTimeFormat format strings. For more information, see Class DateTimeFormat. You can also use the special value millis to parse timestamps in epoch milliseconds. If you don't specify a format, Firehose uses java.sql.Timestamp::valueOf by default.
