> Every once in a while a tablet server will go zombie. The tablet server is
> alive and talking to the master and zookeeper, but not accepting new
> connections from clients. To keep these types of tablet servers from causing
> problems a process could try to scan a tablet on each tablet server
> periodically. If it can not scan a tablet within a certain number of tries,
> it could delete the tservers lock in zookeeper. The monitor process could do
> this.
