Eli Collins commented on HDFS-2391:
-----------------------------------
How about just one info log?
{code}
+ LOG.info("Updating balancer bandwidth from " +
dxcs.balanceThrottler.getBandwidth() + " to " + bandwidth + " bytes/s.");
dxcs.balanceThrottler.setBandwidth(bandwidth);
{code}
> Newly set BalancerBandwidth value is not displayed anywhere
