org.apache.hadoop.hive.serde2.Deserializer
Deserializer a JSON reader (or from a String) into a Map or a bean (depending on boolean flag). Unlike most other JSON readers, this handles circular graphs using the special $id and $idref properties. In addition, $class property, if available, is used to map JSON to JavaBeans. @author A.
