      Description

      Steps to reproduce:

      • Set up a 4-node collection (I did this locally)
      • Use the admin UI to create a collection with the _default configset, 10 shards and 4 replicas each. Make sure to make maxShardsPerNode 10 too.
      • Go ahead and create it.

      The Admin UI cranks away for a bit then says "Collection to Solr lost" and "Collection already exists". However, the collection is created successfully.

      I do see this in the logs:
      ERROR (OverseerThreadFactory-9-thread-2-processing-n:192.168.1.122:8981_solr) [ ] o.a.s.c.a.c.OverseerCollectionMessageHandler Collection: eoe operation: create failed:org.apache.solr.common.SolrException: collection already exists: eoe

      cUrling in this command reports no errors, either on the terminal window or in the logs:
      http://localhost:8981/solr/admin/collections?action=CREATE&name=eoe1&numShards=10&replicationFactor=4&maxShardsPerNode=10&collection.configName=_default
