    Description

      Hadoop 0.18 does not support direct HDFS upgrades from versions 0.13 or earlier as stated in HADOOP-2797.
      A 2 step upgrade is required in this case first from 0.x <= 0.13 to one of version 0.14 through 0.17 and then to 0.18.
      This implies that current hdfs does not need to support code related to conversions of the old (pre 0.13) storage layout to the current one introduced in 0.13 (see. HADOOP-702).
