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

             Summary: Add rolling upgrade information to fsimage
                 Key: HDFS-5945
                 URL: https://issues.apache.org/jira/browse/HDFS-5945
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
            Reporter: Tsz Wo (Nicholas), SZE
            Assignee: Tsz Wo (Nicholas), SZE


When rolling upgrade is in progress, the standby namenode may create checkpoint.  The rolling upgrade information should be added to fsimage in order to support namenode restart and continue rolling upgrade.
