    Description

      Currently TokenCache.obtainTokensForNamenodes() returns immediately if security disabled. This works when DTs are only built from Kerberos creds, but means that filesystems which serve up credentials which don't need kerberos (HADOOP-14556 for S3A, ABFS and WASB can also be enhanced to do this), don't get picked up

      The token cache can just ask each FS for any tokens, relying on them to return null if they aren't generating/forwarding any
