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.
