             Summary: TokenCache.obtainTokensForNamenodes() to get DTs even when security is off
                 Key: MAPREDUCE-7154
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7154
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: client
    Affects Versions: 3.2.0
            Reporter: Steve Loughran


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
