> when ignoreZkOffsets set true and startOffsetTime = kafka.api.OffsetRequest.EarliestTime().
> workers running -> topology shutdown by user and restart -> workers will read from earliest time again
> workers running -> one of workers shutdown by accident and supervisor restart the worker -> what offset will the restarted worker read from?
> More details on https://github.com/apache/storm/pull/493#issuecomment-135783234
