Stack trace after all (single) data node died
> Backoff returned from HDFSEventSink after IOException
> -----------------------------------------------------

> Project: Flume

> Status.Backoff is returned from HdfsEventSink.process() in case of
> IOException. This behavior prevents FailoverSinkProcessor from pushing event
> to next sink in queue.
> In my test case, IOException is caused by serious hdfs failure, for example
> all DataNodes in cluster are dead. After such failure BucketWriter throws
> IOException and becomes unavailable - it probably should be removed from
> sfWriters map.
