------------------------------------

             Summary: Typo in config settings for AvailableSpaceVolumeChoosingPolicy in hdfs-default.xml
                 Key: HDFS-4830
                 URL: https://issues.apache.org/jira/browse/HDFS-4830
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.0.5-beta
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers
            Priority: Minor


In hdfs-default.xml we have these two settings:

{noformat}
dfs.datanode.fsdataset.volume.choosing.balanced-space-threshold
dfs.datanode.fsdataset.volume.choosing.balanced-space-preference-percent
{noformat}

But in fact they should be these, from DFSConfigKeys.java:

{noformat}
dfs.datanode.available-space-volume-choosing-policy.balanced-space-threshold
dfs.datanode.available-space-volume-choosing-policy.balanced-space-preference-percent
{noformat}

This won't actually affect any functionality, since default values are used in the code anyway, but makes the documentation generated from hdfs-default.xml inaccurate.
