Steve Loughran updated HADOOP-4659:
-----------------------------------
Attachment: hadoop-4659.patch
Here's a merged patch that retains the same exception types as before (so the
calling code does not need to look inside nested exceptions), and which
contains the test. The new TestRPC test is correctly detecting failure to
connect.
Where we do have a problem is that on my machine (64-bit JRockit JVM on
Ubuntu), I'm seeing TestFileCreationClient hang and it appears to be in these
methods. Accordingly I'm not setting the patch available flag as it may cause
trouble for Hudson.

> 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.
