Juhani Connolly commented on FLUME-865:
---------------------------------------

I've got a(theoretically) working prototype for this now but ran into a problem 
when testing it with 4 separate agents:
- 1 execsource that was failovering 3 avrosinks, running in the debugger
- 3 agents listening to the above agent, ant sinking to a logger

The problem is, that the AvroSink never sends out EventDeliveryExceptions. 
Furthermore, it fails quite frequently, so if I was just to replace the bit 
with the AvroException, it would be failovering nonstop without retrying a 
couple of times first.
