Chris Douglas updated HADOOP-5348:
----------------------------------

    Status: Open  (was: Patch Available)

I think the plan of record is to standardize on Avro for Hadoop's wire format.

> HADOOP-5201 and other issues would benefit from a stable representation of exceptions,
one that can be sent over the network, maybe pushed out to web UIs and which we can be 100%
sure that the far end will be able to handle if they have the hadoop-core JAR on their classpath.
