> Currently, DemuxManager controls the Demux's reduce number by reading
> "CHUKWA_DEMUX_REDUCER_COUNT_FIELD" at the initialization part. It is
> impossible to tune that reduce number before the next round of demux happens.
> The only way is to restart that DemuxManager service. I wonder if it is OK to
> parse that configuration item in runDemux() function.
