I recently encountered a problem that the SOLR server went down while creating a collection. After SOLR returned to normal, I tried to create the collection again, but the server feedback:'collection already exists'. I checked and found that the znode corresponding to the collection under the Zookeeper /collections path has been created, but the corresponding core was not found in solrHome. After manually deleting the wrong znode under the /collections path, the collection can be successfully created. Is there any other more elegant recovery method besides this?
