-----------------------------------
I am working on this
> levenshtein directly on top of UTF8String

> We currently rely on commons-lang's levenshtein implementation. Ideally, we
> should have our own implementation to:
> 1. Reduce external dependency
> 2. Work directly against UTF8String so we don't need to convert to/from
> java.lang.String back and forth.
