Had an off-list suggestion to make a blog post out of it. I like that
idea. Sounds like a plan to me (since I've kind of failed on
coordinating regular blog posts...)

I had some HBase friends ask me for a design document on how Tablet
assignment in Accumulo works. Their assignment logic continues to be a
pain point and there's been a lot of confusion about wanting to use FATE
for assignments (even moreso when I would tell people: no, that's
unnecessary).
Since we didn't have a good reference document (I'm guessing because it
was designed prior to the initial import of code), I took the time to
write one up based on my understanding of the code and some pointers
from Eric.
Think this deserves a place in our documentation somewhere? Seems like
it's a good reference sheet to have lying around, but I'm not sure where
best it'd be stored.
Huge thanks to Eric for his pointers and editing.
