    I do not think you can run jar compiled with hadoop 0.20.1 on hadoop 0.18.3

    They are not compatible.

    If you're working with the Cloudera distribution, you can install CDH1
    (0.18.3) and CDH2 (0.20.1) side-by-side on your development machine.

    They'll install to /usr/lib/hadoop-0.18 and /usr/lib/hadoop-0.20; use
    /usr/bin/hadoop-0.18 and /usr/bin/hadoop-0.20 to execute, etc.

    See http://archive.cloudera.com/ for installation instructions.
