   > Use case: if the jar’s function definition is changed , user can drop the jar and add back again without restarting the thrift server
   > 
   > Earlier for any changes done to the jar it is required to restart the thrift server as it was added to classpath
   
   If the UDF function jar path does not change, only the update jar is overwritten, can you not start the thriftserver and take effect in real time?
