----------------------------------------
Hi Arun
I have similar setting for 0.23 and Hadoop-0.20.204 with GridMix and same trace
mapred.job.shuffle.input.buffer.percent=0.7 is Hadoop 0.20.204
And
mapreduce.reduce.shuffle.input.buffer.percent=0.7
Hadoop 0.20.204 reducers does not goes OOM, I have seen this in Hadoop.Next
only.
And even in Hadoop 0.23 the behavior is not consistent, random number of job
used fail due to this.
W.r.t to Hadoop-0.20.204 is not a regression
> Gridmix jobs are failing with OOM in reduce shuffle phase.
