1) you can re-balance a node with
bin/nodetool -h <host> token [<new-token>]
specify a new token manually or let the system guess one.
2) take a look into your system.log to find out why your nodes are dying.
i do some INSERT ,because i will do some scan operations, i use the OrderPreservingPartition method.
the state of the cluster is showed below.
as i predicated the load is very imbalance, and some of the nodes down (in some nodes,the Cassandra processes died and in others the processes are
alive but they still down),
so i have two questions:
1)how to do balance after the insert ends?
2)why the nodes died? how to make them up again (when the situation is that the process is alive but the node'state is down)
