Thanks for your effort for fast bug fix! I know that working in the kids
cafe is not easy.
Anyway, I'm happy with the valid query result.
Since this is an issue for the performance improvement, I'd like to see how
fast Tajo is with this feature. So, I'll conduct a simple performance
evaluation on a real cluster within the next few days.
If possible, would you mind testing, too?

> We can improve the query processing performance by executing two or more
> independent ExecutionBlocks if possible.
