    Default How to clear environmental variable?

    Hello --- I use environmental variables for Database connection properties in the .kettle properties file.

    I need to change a database instance from "blah blah" to blank. Just, blank. Nothing. Nada.

    Setting a variable to (blank) doesn't seem to work in jobs. I'm using version 7.1

    Setting a variable to anything changes it. However setting it to blank is like "do nothing, keep old value."

    How do I ACTUALLY set an active variable to blank or clear it out? A javascript sub-job or something?

    Alright I'm using the javascript job entry parent_job.setVariable("MyVariable","") -- but really, not sure why a set variable function can't be set to blank and "clear" the variable potentially. Hmm.
