Steve Loughran commented on HADOOP-5348:
----------------------------------------
This could also be used in the ping operations proposed in HADOOP-3628; these
objects would be lighter weight than a list of exceptions if there was no need
to create stack traces, but easy to marshall
> Create a stable wire format for exceptions

> Key: HADOOP-5348
> URL: https://issues.apache.org/jira/browse/HADOOP-5348
> Project: Hadoop Core
> Issue Type: New Feature
> Components: ipc
> Affects Versions: 0.20.0, 0.21.0
> Reporter: Steve Loughran
>
> 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.
