> 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.
