------------------------------------

             Summary: Collection in ZK not deleted when all shards has been unloaded
                 Key: SOLR-3563
                 URL: https://issues.apache.org/jira/browse/SOLR-3563
             Project: Solr
          Issue Type: Bug
          Components: multicore, SolrCloud
    Affects Versions: 4.0
         Environment: Same as SOLR-3561
            Reporter: Per Steffensen
            Priority: Minor


Same scanario as SOLR-3561 - deleting shards/cores using CoreAdmin/UNLOAD command.

I have noticed that when I have done CoreAdmin/UNLOAD for all shard under a collection, that
the collection and all its slices are still present in ZK under /collections. I might be ok
since the operation is called UNLOAD, but I basically want to delete an entire collection
and all data related to it (including information about it in ZK).

A delete-collection operation, that also deletes info about the collection under /collections
in ZK, would be very nice! Or a delete-shard/core operation and then some nice logic that
detects when all shards belonging to a collection has been deleted, and when that has happened
deletes info about the collection under /collections in ZK.
