URL: https://issues.apache.org/jira/browse/HDFS-10588
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode, hdfs
Reporter: Weiwei Yang
Noticed error message in namenode log
{code}2016-06-28 19:49:12,221 ERROR datanode.DiskBalancer (DiskBalancer.java:checkDiskBalancerEnabled(297)) - Disk Balancer is not enabled.

even with default configuration dfs.disk.balancer.enabled=false.This is triggered when accessing datanode web UI, because {{DataNode#getDiskBalancerStatus}} calls the check.
