Hi,   The JSON class in json-serde-1.3.7-jar-with-dependencies.jar is org.openx.data.jsonserde.JsonSerDe, not com.cloudera.hive.SERDE.JSONSerDe. So did you mean to use com.cloudera.hive.SERDE.JSONSerDe or org.openx.data.jsonserde.JsonSerDe?   Can you give me the output of :   jar tf /usr/lib/hive/lib/hive-serdes-1.0-SNAPSHOT.jar   so that I can confirm the classes in this jar?   Thanks ...
