Chris Douglas commented on HADOOP-4698:
---------------------------------------
+1 For lowering io.sort.mb to 5-10 in the test configuration.
The discussion about raising the memory limit in HADOOP-3644 seemed to trail
off into ambivalence. I agree with Steve's sentiment: it wouldn't be harmful.
Most of the memory issues we'd be worried about are more likely to show up at
scale than in the unit tests.

> 2 test cases in TestMapRed fail when run with 64bit JDK. They both run out
> of memory. This is due to the default value of io.sort.mb being used (100mb).
