Is it possible to install additional libs/dependencies after the cluster is already up and running?
Things I've done that are related to this:
- I've already done the pre-creation bootstrapping process (this is a different solution altogether)
- alternatively, SSH'd into each node and installed dependencies after the cluster comes up
I think the post-startup installation solution would involve being able to fire off a command to all the executors from the driver. Is there a way to accomplish this?
