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.
