-------------------------------------------
BTW, thanks for working on this. It is a good catch!

> HDFS-8826 added a -source flag to the balancer, but the usage message still
> needs to be updated. See current usage message in trunk:
> {code}
> private static final String USAGE = "Usage: hdfs balancer"
> + "\n\t[-policy <policy>]\tthe balancing policy: "
> + BalancingPolicy.Node.INSTANCE.getName() + " or "
> + BalancingPolicy.Pool.INSTANCE.getName()
> + "\n\t[-threshold <threshold>]\tPercentage of disk capacity"
> + "\n\t[-exclude [-f <hosts-file> | <comma-separated list of hosts>]]"
> + "\tExcludes the specified datanodes."
> + "\n\t[-include [-f <hosts-file> | <comma-separated list of hosts>]]"
> + "\tIncludes only the specified datanodes."
> + "\n\t[-idleiterations <idleiterations>]"
> + "\tNumber of consecutive idle iterations (-1 for Infinite) before "
> + "exit."
> + "\n\t[-runDuringUpgrade]"
> + "\tWhether to run the balancer during an ongoing HDFS upgrade."
> + "This is usually not desired since it will not affect used space "
> + "on over-utilized machines.";
> {code}
