Configuration upload to zookeeper and collection creation are two separate things, although they can be accompished at the same time using /bin/solr. You can upload configurations before you create collections and you can have mutiple configurations uploaded to zookeeper at the same time. I typically upload my configurations using zkcli.sh in the server/scripts/cloud-scripts directory in Solr and then use curl to send a request to create the collection based on a configuration I uploaded to Zookeeper instead of using the /bin/solr script to do the upload and creation all at once. So you may have several configs uploaded, but you may not necessarily have created collections for them.
If you need to update the configuration, just re-upload using zkcli.sh (from Solr server/scripts/cloud-scripts not ZkCli.sh in zookeeper/bin) and then try the collection creation again using curl or the browser to issue the Collections API create command. Re-uploading will overwrite the config in Zookeeper. I don't believe what you are seeing is a bug, as you can upload anything you want to Zookeeper, but it doesn't mean it's valid. Only Solr knows that once it tries to load what you've uploaded to Zookeeper. - Kevin > On Sep 3, 2015, at 12:36 AM, shacky <shack...@gmail.com> wrote: > > Hi Shalin, > thank you very much for your answer. > > I found out and managed in recreating the problem. > > I created a new collection, with the wrong configset.
