> 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.
