The developer's machine is Hadoop 0.20.1, Jar is compiled on the developer's machine.
The server is Hadoop 0.18.3-cloudera. How can I run my mapreduce program on the server?

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.
