  Does cassandra support the load balance? Is StorageLoadBalancer in charge of this job? I find so many codes have beed commented out in this class.

LoadBalance is implemented as (1) leave the ring, (2) rejoin in the
new position.  Look at StorageService.loadBalance.
StorageLoadBalancer is there for when we automate the balance process
for nodes that are under-loaded relative to the rest of the cluster.
It won't be hard to turn on, but we want to get the core node movement
stuff very solid before enabling that.
