> 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.
