Re: exception
This is a Hadoop DFS error. It could mean that you don't have any datanodes running, or that all your datanodes are full. Or, it could be a bug in dfs. You might try a recent nightly build of Hadoop to see if it works any better.

TRUNK IllegalArgumentException: Argument is not an array (WAS: Re: exception)
I'm getting same as Anton below trying to launch a new job with latest from TRUNK. Logic in ObjectWriteable#readObject seems a little off. On the way in we test for a null instance. If null, we set to NullWriteable. Next we test declaredClass to see if its an array. We then try to do an Array.getLength on instance -- which we've above set as NullWriteable. Looks like we should test instance to see if its NullWriteable before we do the Array.getLength (or do the instance null check later).
