> This comes particularly useful in clusters that have a split between DNs used for regular
purpose and DNs used for HBase RSes specifically. By asking the balancer to exclude the DNs
that RSes run on, its possible to avoid impacting HBase's local reads performance, and the
balancing of these nodes can be deferred to a later time.
> An alternate, and perhaps simpler approach would be to make the Balancer file-aware and
ask it to skip a specific directory's file's blocks (i.e. that of /hbase for example).
