---------------------------------

             Summary: Checkpointing should use monotonic time when calculating 
period
                 Key: HDFS-5591
                 URL: https://issues.apache.org/jira/browse/HDFS-5591
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.2.0
            Reporter: Andrew Wang
            Priority: Minor


Both StandbyCheckpointer and SecondaryNameNode use {{Time.now}} rather than 
{{Time.monotonicNow}} to calculate how long it's been since the last 
checkpoint. This can lead to issues when the system time is changed.
