Subject Reduce Merge Memtomem Parameter
Date Fri, 25 Oct 2013 20:20:30 GMT
Hi All,

What do "mapreduce.reduce.merge.memtomem.threshold" and "mapreduce.reduce.merge.memtomem.enabled"
do and by default is it enabled? There's no documentation for them but I noticed that they
exist in hadoop 2.2.0.

Thanks!
