> {{AvroMode}} uses the same configuration property for both shuffle and bundle configuration.
If the bundle's AvroMode for a map/reduce round doesn't match the shuffle's AvroMode, then
the bundle wins. In some cases, this prevents the shuffle from being able to write data, e.g.,
because GENERIC is used instead of REFLECT.
> A work-around if to set the strict mode to delegate reader and writer construction to
the more permissive one:
> {code:java}
> AvroMode.GENERIC.override(AvroMode.REFLECT);
> {code}
