I like it. But I think it needs some functionality for verifying
parameters. To let the user specify some parameters that always need to be
there and a description of the parameter. Similar to how other tools print the
"usage" when you don't give correct arguments.
> Provide utils to pass -D parameters to UDFs

> Hadoop users are used to setting job configuration through "-D" on the
> command line.
> Right now, Flink users have to manually parse command line arguments and pass

> It would be nice to provide a standard args parser with is taking care of
