When using MapReduce job to perform an incremental load into a table,the number
of reduce tasks is the current number of regions. If there are too many
regions, will lead to network+disk I/O is too large, affecting the real-time
request.
Need to use a configuration to set a number or ratio?
Limit running reduce tasks since
[https://issues.apache.org/jira/browse/MAPREDUCE-5583], the old version can
only be set reduce number.
