Yu Li commented on HDFS-6010:
-----------------------------

Hi [~devaraj],

Sorry for bothering but I noticed you contributed HDFS-2576, and since the patch here is a
tool for an io-isolation solution based on favored node feature, could you help review? I've
also submit a rb request [here|https://reviews.apache.org/r/18504/]

Thanks in advance!

> Currently, the balancer tool balances data among all datanodes. However, in some particular
case, we would need to balance data only among specified nodes instead of the whole set.
> In this JIRA, a new "-servers" option would be introduced to implement this.
