Description

I have a setup like this:

agent: source | agentDFOChain("collector1:35853", "collector2:35853")

collector1: collectorSource(35853) | collectorSink("hdfs://namenode.company.net:54310/flume/", "%Y_%m_%d_%H-")

collector2: collectorSource(35853) | collectorSink("hdfs://namenode.company.net:54310/flume/", "%Y_%m_%d_%H-")

If both collectors are running, and then collector1 gets into an ERROR state (such as because of the FLUME-798), events are silently dropped. No fail-over takes place to the other node in the chain, and no events are written to disk.
