Hi,
I have a hive table which uses the jar file provided from the elephant-bird, which is a framework integrated between lzo and google protobuf data and hadoop/hive.
If I use the hive command like this:
hive --auxpath path_to_jars, it works fine to query my table,
but if I use the add jar after I started the hive session, I will get ClassNotFoundException in the runtime of my query of the classes in those jars.
My questions are:
1) What is the different between hive --auxpath and "add jar" in the hive session?2) This problem makes it is hard to access my table in the HUE, as it only supports "add jar", but not --auxpath option. Any suggestions?

Thanks
Yong    

If properly done, "add jar <jar-file>" should work the same as passing the jar with --auxpath. Can you run "list jars;" command from CLI or Hue and check if you see the jar file.

--auxpath adds more jars to Hive's classpath before invoking Hive. ADD JARS
copies jars around the cluster and adds them to the task classpath, so the
jars you add aren't visible to hive itself. Annoying, but...

Essentially anything that is part of the InputFormat needs to be in
auxlib/auxpath. Anything part of a UDF can be added with 'add jar'.

I am not sure whether it works but try this:

Put your ADD JAR commands into a file and invoke hive with -i file option.

or

insert your ADD JAR commands in your $HOME/.hiverc file and start hive.
