using solr 4.4 , i used collection admin to create a collection 4shards replication - factor of 1
i did this so i could index my data, then bring in replicas later by adding cores via coreadmin i added a new core via coreadmin, what i noticed shortly after adding the core, the leader of the shard where the new replica was placed was marked active the new core marked as the leader and the routing was now set to implicit. i've replicated this on another solr setup as well. Any ideas? Thanks msj
