    Description

      In SolrCloud, it is possible for a core to come up in any node , and register itself with an arbitrary slice/coreNodeName. This is a legacy requirement and we would like to make it only possible for Overseer to initiate creation of slice/replicas

      We plan to introduce cluster level properties at the top level

      /cluster-props.json

      {
"noSliceOrReplicaByCores":true"
}

      If this property is set to true, cores won't be able to send STATE commands with unknown slice/coreNodeName . Those commands will fail at Overseer. This is useful for SOLR-5310 / SOLR-5311 where a core/replica is deleted by a command and it comes up later and tries to create a replica/slice
