+You should use the uberjar when starting the profiler in this manner so that all the profiler's dependencies are available.

 The profiler can also be loaded dynamically (after the JVM has already started), but this technique requires relying on Sun's `tools.jar`, meaning it's an implementation-specific solution that might not work for all JVMs. For more information see the [Dynamic Loading section](#dynamic-loading-of-agent). 
 
 An example of setting up Cascading/Scalding jobs to use the profiler can be found in the `example` directory.
