             Summary: ConfigSetsHandler requires DIR entries in the uploaded ZIPs
                 Key: SOLR-15858
                 URL: https://issues.apache.org/jira/browse/SOLR-15858
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: configset-api
    Affects Versions: 8.11.1
            Reporter: Andrzej Bialecki


If you try uploading a configset zip that contains resources in sub-folders - but doesn't contain explicit DIR entries in the zip file - the upload will fail with `NoNodeException`.

This is caused by `ConfigSetsHandler.createZkNodeIfNotExistsAndSetData` which assumes the entry path doesn't contain sub-path elements. If the corresponding DIR entries are present (and they occur earlier in the zip than their child resource entries!) the handler will work properly because it recognizes DIR entries and creates ZK paths as needed.

The fix would be to always check for the presence of `/` characters in the entry name and make sure the ZK path already exists.
