Eric Newton commented on ACCUMULO-1937:
---------------------------------------
If the master assigns a tablet, but then comes back and unassigns it, there's a
race in which the assignment handler can start the assignment, but the tablet
is no longer in the unopened list.

> Project: Accumulo
> Issue Type: Bug
> Reporter: Eric Newton

> Priority: Minor
> Fix For: 1.6.0
>
>
> Running a single node random walk test with two walkers. I got this error
> message several times.
> The way I read this: an assignment was not found in the unopened tablets
> list. But unopened, opening and online tablets are all empty.
> Need to figure out if this condition warrants an error message and squash it
> if it does not.
