I didn't realize that you were trying to use your own AMI! The procedure on the wiki for building your own is based on using the core Fedora AMI. I did try using an Ubuntu one some time back but got into difficulties with networking, so I've used the official Fedora one since then. Anyway, glad you've got something working. > I've also moved up to Hadoop 0.14.1 and hand-applied the fix from > HADOOP-1783.

There is a patch for HADOOP-1783 (see the Jira attachment) which fixes the issue - the one-liner didn't fix unit tests. This didn't make the 0.14.1 release but it will make the next one. Cheers, Tom
