> Testing some node recovery operations.
> In this case:
> 1. Data is being added/updated as it would in production
> 2. repair is running on other nodes in the cluster
> 3. we wiped data on this node and started up again, but before repair was actually started
on this node (but it had gotten data through the regular data feed) we got this error.
> I see no indication in the logs that outgoing streams has been started, but the node
have finished one incoming stream before this (I guess from some other node doing repair).
