Description

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

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

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

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

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.
