      Description

      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.
