> {{AvroTupleWrapper}}, {{AvroMapWrapper}} and {{AvroBagWrapper}} expose write APIs but their implementation is broken. 
> For instance, we can do 
> {code}
> Tuple t = TupleFactory.newInstnace().newTuple(1);
> t.set(0, 0);
> avroTupleWrapper.set(0, t);
> avroTupleWrapper.get(0);  
> {code}
> The last line will (in most cases) fail depending upon what the avro schema is for the 0th element.
> I'm attaching a patch which highlights this more concretely. The patch only shows failures in AvroTupleWrapper but similar problems exist in corresponding Map and Bag classes
