> We have seen occassional RSW reboots in the production cluster.
> On the client end, the reduction in the operation throughput is a lot more
> than the %-age of nodes disconnected. This is because operations to the
> disconnected machines are holding up resources that could otherwise be used
> for successful operation.
> This change enables the client to detect when there are repeated failures to
> a regionserver, and fast fail operations so we do not hold up resources.
