>             Project: Hadoop Core
>          Issue Type: Improvement
>          Components: dfs
>    Affects Versions: 0.17.0

> 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).
