             Summary: Fix root deletion logic in delete API
                 Key: HDDS-2973
                 URL: https://issues.apache.org/jira/browse/HDDS-2973
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
            Reporter: Ayush Saxena
            Assignee: Ayush Saxena


Logic to prevent root from being getting deleted seems to be not working.

{code:java}
      if (key.equals("/")) {
        LOG.warn("Cannot delete root directory.");
        return false;
      }

If it is root, the key will be empty not "/", As pathToKey() will remove the "/" and make it "" and there after addTrailingSlashIfNeeded() will not add a slash as it has a check !isEmpty(key) before adding slash.
{code}
