[jira] [Created] (HDFS-7042) Upgrade fails for Windows HA cluster due to file locks held during rename in JournalNode.

Chris Nauroth created HDFS-7042:
-----------------------------------

             Summary: Upgrade fails for Windows HA cluster due to file locks held during rename in JournalNode.
                 Key: HDFS-7042
                 URL: https://issues.apache.org/jira/browse/HDFS-7042
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: journal-node
    Affects Versions: 2.4.1
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth
            Priority: Blocker


During upgrade of an HA cluster, the JournalNode attempts to rename the current storage directory to previous.  However, the process still holds the last committed transaction ID file opened while this is happening.  On Windows, this is a locking violation that causes the rename operation to fail.  Ultimately the whole upgrade fails.  There is a similar problem during rollback too.
