> In standalone mode, when a worker gets disconnected from the master for some
> reason it never attempts to reconnect. In this situation you have to bounce
> the worker before it will reconnect to the master.
> The preferred alternative is to follow what Hadoop does -- when there's a
> disconnect, attempt to reconnect at a particular interval until successful (I
> think it repeats indefinitely every 10sec).
