NameNode should save image to name directories in parallel during upgrade
-------------------------------------------------------------------------

                 Key: HDFS-1826
                 URL: https://issues.apache.org/jira/browse/HDFS-1826
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
    Affects Versions: 0.23.0
            Reporter: Hairong Kuang


Currently namenode saves a new image to all its name directories in sequence during upgrade.
We should make it to do in parallel to speedup namenode upgrade. Also it should not save its
image to edits directories.
