What happens if a scheduler registers with a framework ID that hasn't been used in 48 hours?

[David Greenberg <ds...@gmail.com>]

I don't recall the exact timeout of framework IDs, but what I'm wondering
is what happens if a scheduler tries to "failover", but the failover grace
period has elapsed? Does it fail to register, or does it successfully
register and all the old executors are just gone?

Note that frameworks can set their own failover timeout.

If a framework is disconnected for more than the failover timeout duration,
all its executors/tasks are killed.

If a framework tries to re-register with a "framework id", *currently* the
master allows it. In the future (when master has persistent state about the
frameworks) this will be disallowed.
