Feature request: System recovery on node failure about glu HOT 2 OPEN

I think I understand what you are asking. glu has been designed from the very beginning to not do anything automatically. It was a conscious decision. glu has been designed as a platform on top of which you can build this kind of behavior.

In your case, what would need to happen: the static model needs to be modified and glu needs to "deploy" it. It is not very obvious how to handle the modification of the model in an automated fashion since it is essentially a black box to glu and would obviously be very different from customer to customer.

Where I think glu could help would be in providing a hook to plug in some behavior that is triggered when errors are detected. As you mention you can listen to ZooKeeper yourself outside of glu but it seems that since glu is notified of errors, it might be easier to provide a hook directly in glu.

I will think about it.

You can't just start software up on another node blindly. Yes, Marathon will do that, but it obviously requires the software to be stateless (or at least use non-local storage for whatever it does).

With regards to Mesos, it might be interesting to implement af mesos framework (or just executor) for glu. :-)
