Re: [DISCUSSION] Accumulo, another BigTable clone, has shown up on Apache Incubator as a proposal

Accepting Accumulo into the incubator would be a good encouragement for the
folks at NSA to work more with open source software and engage with the
communities and set a good example for future projects. That, in my mind,
seems to be the strongest reason for letting the project in. However, I
don't see how that helps HBase or ASF in the long run. It is true that it'll
take time and effort to combine the projects right now but that might be a
hit worth taking and having combined development efforts from here on as
compared to having two completely independent project and later on looking
at the merge. I don't see how a merge later on will be any easier than right
now. The decision obviously comes down to how much effort the developers on
both projects are willing to put into it right now or later on.

Having said that, I think the HBase community at large needs to get an
insight into Accumulo's implementation to gauge how different the two
projects are in terms of the implementation details and code. Trying to come
to a conclusion without doing that might not give us the best solution. I'm
excited about the fact that we have an alternate implementation but that's
just the engineer in me. The HBase user in me is worried about the confusion
an almost ditto alternate project will create.

Just my $0.02.
