Subject Re: difference between add jar in hive session and hive --auxpath
Date Sat, 09 Mar 2013 17:32:41 GMT
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.
