--------------------------------
Summary: Re-configure Demux ReduceNumber without re-starting the
DemuxManager service
Key: CHUKWA-650
URL: https://issues.apache.org/jira/browse/CHUKWA-650
Project: Chukwa
Issue Type: Improvement
Components: Data Processors
Affects Versions: 0.6.0
Reporter: Jie Huang
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.
