> 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."
