I suggest to start with fault injection tests. They can found under
src/test/aop/org/apache/hadoop
for HDFS in 0.22. Hdfs has been has the best coverage by fault injection.
Test exists in the similar location in the trunk, but they aren't hooked up to
maven build system yet.

Why do you want multiple users starting daemons?
As for submitting jobs, that should work out of the box. If you want the child
JVMs running the map and reduce tasks to execute as the submitting user, then
you need to configure your cluster with Kerberos.

Try pinging http://repo2.maven.org/maven2/org/apache/ivy/ivy/2.2.0/ivy-2.2.0.jar
to see if your server can connect to that URL.
If not you have some kind of connection issue with outgoing requests.

Hi
Check the `mapreduce.job.reduce.slowstart.completedmaps` parameter. The
reducers cannot start processing the data from the mappers until the all
the map tasks are complete, but the reducers can start fetching the data
from the nodes on which the map tasks have completed.

Can you ping any URL successfully?
Try www.google.com, www.yahoo.com or something like that.
If you can't ping any of those then you are probably behind a firewall

Or you can download the jar that it is trying to find

Looks like you may have an unsupported/older version of ant.
May try upgrading ant to something over 1.7
