Luke Lu updated MAPREDUCE-1617:
-------------------------------
Attachment: mr-1617-trunk-v2.patch
Good catch, Amarsri. I was testing the jvm default (-Xmx500m) vs -Xmx200m to
see if the larger default Xmx makes the tests run faster. For the curious,
there is no statistical difference in cold runs. However, in repeated tests,
the smaller Xmx is actually significantly faster.
> TestBadRecords failed once in our test runs
