             Summary: Solrcloud change core to another shard issue
                 Key: SOLR-5071
                 URL: https://issues.apache.org/jira/browse/SOLR-5071
             Project: Solr
          Issue Type: Bug
          Components: SolrCloud
            Reporter: Illu Y Ying


I have a solrcloud cluster with one collection and two shards.
One core is a replica for shard1, I stop it and change its solr.xml like this:
<core name="collection1" instanceDir="collection1" shard="shard2"/>
So this core should be a shard2 replica, Then I restart it, open cloud graph page, you can see this core as a down replica still in shard1 and also as a active replica in shard2.
So I would like to suggest you to remove the down replica information from clusterStatus.json.
There is doubt about one core status in two shards.
In this one core has two status scenario I suggest that if we could remove the down replica information of other shard in clusterStatus.json.
I remember when core is changing to active status, it will send overseer an active status message, so add this logic to overseer change core to active status part.
