> ipc.Client the root cause of a connection failure is being lost as the exception is wrapped,
hence the outside code, the one that looks for that root cause, isn't working as expected.
The results is you can't bring up a task tracker before job tracker, and probably the same
for a datanode before a  namenode. The change that triggered this is not yet located, I had
thought it was HADOOP-3844 but I no longer believe this is the case.
