> In Phoenix, we'd like to add some Phoenix-specific commands in support of our UDF implementation. For example, we'd like to add commands like to manage the jars containing the implementation of the UDFs:
> - {{ALTER SYSTEM ADD JAR ...}}
> - {{ALTER SYSTEM LIST JARS}}
> Without copy/pasting the entire parser grammar for the command (see comment here[1]), it seems there's no easy way to do it. Perhaps we're missing something and there's already an easy way?
