Andrew Wang created HDFS-5591: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.1#6144)
