Arun C Murthy commented on MAPREDUCE-430:
-----------------------------------------
I guess we should continue to debate the semantics of exception-handling in a
separate jira - and get this in as an emergency fix.
Wrt the patch, I'd be happier to with 2 changes:
# Don't rethrow exceptions:
# 'Unwrap' to get the 'cause' in Child.java
(http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Throwable.html#getCause%28%29).
Thoughts?
