> When troubleshooting HBase-input MR job map failures, the TableSplit's
> toString() definition comes very handy. However, it still does not tell us
> directly which region ID it was created for (it does tell us the key and the
> host, but not the exact region name, so there's a second lookup needed from
> the UI to find the ID to then check the servers with).
> It would be beneficial to have the encoded region name as part of the output,
> so this extra manual lookup can be avoided. The encoded name is much easier
> to find events with.
