Mark Miller commented on SOLR-5311:
-----------------------------------

Shalin has captured previous discussions really well in this issue SOLR-5128. We need a new
"ZooKeeper is Truth" mode. In that mode, we can start building this feature set out.

> If a replica is removed from the clusterstate and if it comes back up it should not be
allowed to register. 
> Each core ,when comes up, checks if it was already registered and if yes is it still
there. If not ,throw an error and do an unregister . If such a request come to overseer it
should ignore such a core
