> Here I propose a very simple TablePool.
> It could be called LightHTablePool (or something - if you have a better name).
> Internally it would maintain an HConnection and an Executor service and each invocation of getTable(...) would create a new HTable and close() would just close it.
> In testing I find this more light weight than HTablePool and easier to monitor in terms of resources used.
> It would hardly be more than a few dozen lines of code.
