------------------------------

Integrated in Hadoop-Hdfs-trunk #685 (See [https://builds.apache.org/hudson/job/Hadoop-Hdfs-trunk/685/])
    HDFS-2020. Fix TestDFSUpgradeFromImage by removing the use of DataNode as a singleton.

the singleton can point to only one of the datanodes. TestDFSUpgradeFromImage fails related
to initialization of this singleton.
