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.
