> Since the failover timeout was added, you get a lot of weird behavior in clusters running frameworks that don't support failover due to its long default value of 1 day. If a framework fails or just exits without calling driver.stop(), all its executors stay around and consume resources on the machines, causing subsequent runs to mysteriously fail to acquire resources. See http://groups.google.com/group/spark-users/msg/553af12424e4ed3d for an example. I know that the failover timeout is supposed to eventually become a per-framework parameter anyway, but in the meantime, the easiest way to prevent this is to set it to 0, because almost no users have failover-enabled frameworks.
