Varun Saxena commented on MAPREDUCE-6223:
-----------------------------------------
Oops, that came out really bad. I meant the test below. :)
{code}
@Test
public void testNegativeValuesForMemoryParams() {
JobConf configuration = new JobConf();
configuration.set(MRJobConfig.MAP_MEMORY_MB, "-5");
configuration.set(MRJobConfig.REDUCE_MEMORY_MB, "-6");
Assert.assertEquals(-5, configuration.getMemoryForMapTask());
Assert.assertEquals(-6, configuration.getMemoryForReduceTask());
}
{code}
