While IANAL... As long as any implementation follows Apache's license regarding derivative works, it's fair game. (this is my understanding YMMV)
The APL is very liberal in what one can do with a derivative work... Surely Apache has some lawyers who can summarize what is allowable when talking about a derivative work and what is not? Note these are my opinions only and do not reflect the opinions of anyone else. Any resemblance to a coherent thought is pure coincidence..... Sent from a remote device. Please excuse any typos...

Furthermore, there's the issue of any google patents -while google have given Hadoop permission to them, that may not apply to other things that implement compatible APIs.
