> We need a nice way of handling long network partitions without impacting a master cluster
(which pushes the data). Currently it will just retry over and over again.
> I think we could:
>  - Stop replication to a slave cluster if it didn't respond for more than 10 minutes
>  - Keep track of the duration of the partition
>  - When the slave cluster comes back, initiate a MR job like HBASE-2221 
> Maybe we want less than 10 minutes, maybe we want this to be all automatic or just the
first 2 parts. Discuss.
