Boris Shkolnik updated HDFS-1714:
---------------------------------

    Attachment: HDFS-1714.patch

Currently there is single Upgrade object in the DataNode. And it makes use of assumption that
there is only one
NameNode by accessing datanode.namenode member. We remove this memeber and make  UpgradeManager
member of BPOffService.
One instance will be created per BPOferService at start.
