Steve Loughran commented on HADOOP-5348:
----------------------------------------
It's certainly part of HADOOP-3628, and is on that branch, but my little
HADOOP-5621 junit runner also uses it for reporting structured test failures
-so it is more broadly useful than just service management.
> Create a ThrowableWritable for serializing exceptions robustly

> 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.
