Weiwei Yang created HDFS-10588:
----------------------------------

             Summary: False alarm in namenode log - ERROR - Disk Balancer is not enabled
                 Key: HDFS-10588
                 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.
{code}
even with default configuration dfs.disk.balancer.enabled=false.This is triggered when accessing
datanode web UI, because {{DataNode#getDiskBalancerStatus}} calls the check.
