Haibo Chen commented on MAPREDUCE-6673:
---------------------------------------
Thanks [[email protected]] for the patch. Two nits,
1) We should probably add description of the behavior of growing memory usage
over time in the class javadoc
2)
bq. LOG.info("Free = " + free + ". Creating 1 MB on the heap.");
can be LOG.info("Free memory = " + free + " bytes. Creating 1MB on the heap");
The patch no longer applies cleanly to trunk, otherwise LGTM.
> Add a test example job that grows in memory usage over time

> While working on YARN-1011, I needed to put together an example that would
> have tasks increase their resource usage deterministically over time. It
> would be useful for any other utilization related work or stress tests.
