Hi Chris, Thanks for your reply. I submitted a patch for MAPREDUCE-2454. I got this failing test error and I am blocked on this. Can you please advise me how I proceed submitting the patch? I can spend some time investigating how to make the test more deterministic if that is possible(either tuning some of the parameters or increasing child JVM memory?)

The "flakiness" you observe is common to many Hadoop integration tests. The purpose of the test is to verify that 1) the merge works when some segments are retained in memory during the reduce 2) the tuning parameters for the reduce have the expected effect. -C On Thu, Jun 7, 2012 at 1:13 PM, Asokan, M <maso...@syncsort.com> wrote: > Can someone guide me in making the test > org.apache.hadoop.mapred.TestReduceFetchFromPartialMem less flaky?
