> We have come across this situation multiple times where a zookeeper issues
> can cause NodeFailoverWorker to fail picking up replication queue for a dead
> region server silently. One example is when the znode size for a particular
> queue exceed jute.maxBuffer value.
> There can be other situations that may lead to this and just go undetected.
> We need to have a metric for number of unclaimed replication queues. This
> will help in mitigating the problem through alerting on the metric and
> identifying underlying issues.
