Jothi Padmanabhan commented on HADOOP-6029:
-------------------------------------------
bq. Nicholas, can you please upload the logs of the test where you see
testReduceFromMem failing (as on the jira description).
Just to clarify -- could you upload the logs where testReduceFromMem failed.
We are able to get testReduceFromPartialMem fail consistently on some machines,
but testReduceFromMem is passing.
> TestReduceFetch failed.
