> I see double-assign during a rolling restart test. Its happening when master
> joins existing cluster... half the RSs have reported in but its taking on
> splits anyways (I have it splitting and balancing continuously). A split
> comes in immediately followed by a balance. What I think is happening is
> that the split comes in and clears a CLOSING from RIT as part of its cleanup
> of parent region references. This is messing up the run of balancers' close
> somehow; we're getting node created and children changed zk events and this
> makes somehow for the double closed.
> I'm enabling zk logging and will try harder to hunt this one down.
> Not creating as BLOCKER on 0.90.0 because I think its ok to disable balancer
> while rolling restart is going on -- and the current rolling restart is a
> horror anyways doing its maximmal region moving.
