Allen Wittenauer resolved HDFS-1293.
------------------------------------

    Resolution: Fixed

Closing this as fixed since it's possible to dynamically reconfigure this one now.

> The dfs.balance.bandwidthPerSec parameter is read at Datanode start time. It would be
nice to allow this parameter to be passed in when the balancer is invoked so, for example,
it can be run during off-peak hours with a higher bandwidth setting.
