> 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.
