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).
Hope above helps,

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.
