Hi all, I have a Hive table which relies on a JSON SerDe to read the underlying files. When I ran the create script I specified the SerDe and it all went fine and the data was visible in the views above the table. When I tried to query the table directly, though, I received a ClassNotFound error. I solved this by putting the SerDe JAR in /usr/lib/hive/lib.
Now, however, when I try to query the data I get: Failed with exception java.io.IOException:org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.ClassCastException: org.json.JSONObject cannot be cast to [Ljava.lang.Object; (The serde is the json serde provided by Apache) Can anyone suggest why it was working before, but no longer is? Thanks, Charles
