Handle multiple Combine LivySession instances #305

Closed ghukill closed 5 years ago

ghukill commented 5 years ago

The GUI attempts to prevent multiple LivySessions from existing, but it's possible in the following ways:

quickly clicking "Restart Livy Session" button

Need to handle multiple instances, either by preventing outright, or facilitating their removal.

Thanks to @colehudson for observing this.

Addressed. Multiple instances of Combine LivySession can still be created, as can multiple Livy sessions, but the GUI can now handle that, and give a user course to remove and restart. Additionally, polling is not infinite when restarting, timeout is 120 seconds.
