    I think it should be possible to specify multiple metastore listeners. Can you please make the following changes:
    
    * Change the name of the conf property from "hive.metastore.listener" to "hive.metastore.event.listeners" and update the description to indicate that this is a comma separated list of listener classnames.
    
    * Change the default value for this property to be an empty string.
    
    * Update the code that initializes these listeners. You can cut and paste the code that's used to initialize hive.exec.pre.hooks
    

- Carl
