Doug Cutting commented on HADOOP-419:
-------------------------------------
Previously different configurations and threads were permitted to use different
classloaders. After this patch, all use the same classloader. I'm not sure
that's always right. Ideally, shouldn't Configuration.getResource() and
Configuration.getClass("foo.class") be able to refer to configuration-specific
resources, like the job jar?
