> SOLR-5476 depends on Overseer restart.The current strategy is to remove the
> zk node for leader election and wait for STATUS_UPDATE_DELAY +100 ms and
> start the new overseer.
> Though overseer ops are short running, it is not a 100% foolproof strategy
> because if an operation takes longer than the wait period there can be race
> condition.
