customizable avro flume interchange - DefaultAvroSource/DefaultAvroSink added
Review Request #3359 - Created Jan. 4, 2012 and updated
AvroSource / AvroSink concrete classes has injectible eventHandlers (SourceEventHandler and SinkEventHandler), to allow for diffrerent avro protocols to be sent over flume NG. ( not restricted to AvroSourceProtocol , as it stands today). Default implementation refers to AvroSourceProtocol still though.
