[jira] [Created] (HDFS-4477) Secondary namenode may retain old tokens

Kihwal Lee created HDFS-4477:
--------------------------------

             Summary: Secondary namenode may retain old tokens
                 Key: HDFS-4477
                 URL: https://issues.apache.org/jira/browse/HDFS-4477
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: security
    Affects Versions: 0.23.7
            Reporter: Kihwal Lee


Upon inspection of a fsimage created by a secondary namenode, we've discovered it contains very old tokens. These are probably the ones that were not explicitly canceled.  It may be related to the optimization done to avoid loading fsimage from scratch every time checkpointing.
