In current hadoop documentation, it is "hadoop balancer [-threshold <threshold>]" to start a balancer and to stop the balancer press ctrl-c.
But in some other places (YDN and older hadoop version documentation), call
"start-balancer.sh" to start it and call "stop-balancer.sh" to stop it. And I
guess start-balancer.sh can also take an optional argument "[-threshold
<threshold>]", right?
Which one is recommended for hadoop 0.20 (I am using CDH3 hadoop-0.20.2+228)?
Thanks,
Michael
