A default external UDF Library Deployment folder is created when you install MashZone NextGen at <MashZone NextGen installation>/raql-udfs where you can deploy all your user-defined functions.
In clustered environments, you may want to create a shared external folder for MashZone NextGen configuration and move all user-defined functions, including the MashZone NextGen built-in function library, to this shared location for all members of the cluster.
If you move user-defined functions from the default UDF Library Deployment folder, you must also update an environmental variable for each MashZone NextGen Server:
<MashZone NextGen installation>/apache-tomcat/bin/setenv.bat file, for Windows systems, or
<MashZone NextGen installation>/apache-tomcat/bin/setenv.sh file for Linux, OS/X or UNIX systems.
