Well, in my cluster, I do this: 1. Adding new machines into conf/slaves on master machine 2. On the new nodes, run format command 3. Back to master, run start-all.sh 4. Run start-balancer.sh , still on master
Then I got the new nodes inside my cluster and no need to reboot the whole system. Hopefully this will help. ;=) Ski Gh3 写道: > I'm not sure I get this. > 1.
