Jing Zhao created HDFS-5968:
-------------------------------

             Summary: Fix rollback of rolling upgrade in NameNode HA setup
                 Key: HDFS-5968
                 URL: https://issues.apache.org/jira/browse/HDFS-5968
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Jing Zhao
            Assignee: Jing Zhao


This jira does the following:
1. When do rollback for rolling upgrade, we should call FSEditLog#initJournalsForWrite when initializing editLog (just like Upgrade in HA setup).
2. After the rollback, we also need to rename the md5 file and change its reference file name.
3. Add a new unit test to cover rollback with HA+QJM
