> I just saw that there's no documentation on how to count rows. Basically there's:
>  - The "count" command in the shell, it's quite fast when configured with the right CACHE.
>  - The "rowcounter" MR job, it's super fast but you need to have a MapReduce setup in
place in order to use it.
> There's also a way to estimate the row count by using the HFile tool and doing a bit
of bash magic.
