> In http://hadoop.apache.org/docs/r1.2.1/distcp2.html#UpdateAndOverwrite
> The first statement of the "Update and Overwrite" section says:
> {quote}
> -update is used to copy files from source that don't exist at the target, or have different
contents. -overwrite overwrites target-files even if they exist at the source, or have the
same contents.
> {quote}
> The "Command Line Options" table says :
> {quote}
>   -overwrite: Overwrite destination
>   -update: Overwrite if src size different from dst size
> {quote}
> Based on the implementation, making the following modification would be more accurate:
> The first statement of the "Update and Overwrite" section:
> {code}
> -update is used to copy files from source that don't exist at the target, or have different
contents. -overwrite overwrites target-files if they exist at the target.
> {code}
> The "Command Line Options" table:
> {code}
>   -overwrite: Overwrite destination
>   -update: Overwrite destination if source and destination have different contents
> {code}
> Thanks.
