> The help message for the command "hdfs dfs -help df" is displayed like this:
> "-df [<path> ...]: Shows the capacity, free and used space of the
> filesystem.
> If the filesystem has multiple partitions, and no path to a
> particular partition is specified, then the status of the root
> partitions will be shown."
> and the information about df -h option is missed,despite the fact that df -h
> option is implemented.
> Therefore,the expected message should be displayed like this:
> "-df [-h] [<path> ...]: Shows the capacity, free and used space of the
> filesystem.
> If the filesystem has multiple partitions, and no path to a
> particular partition is specified, then the status of the root
> partitions will be shown.
> -h Formats the sizes of files in a human-readable fashion
> rather than a number of bytes."
