Hairong Kuang updated HADOOP-4659:
----------------------------------
Attachment: rpcConn1.patch
Hi Steve, I already have a patch which uses most of the code in your previous
patch. You have a very clean programming style. :-) The change that you may not
like is that all exceptions are still wrapped. Please let me know what you
think. Since you are busy, I will be happy to do the testing etc.
> Root cause of connection failure is being lost to code that uses it for
> delaying startup

> 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.
