The output on MAPREDUCE-4094 is no longer available, but a failed job during an integration test could be traced to nondeterminism anywhere in that chain. 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?
