Zac Zhou commented on YARN-9161:
--------------------------------
I checked the failed test case TestRunJobCliParsing and found that it's related
to memory resource API.
In the test case：
{code:java}
// W/o unit for memory means bits, and 20 bits will be rounded to 0
res = CliUtils.createResourceFromString("memory=20,vcores=3",
ResourceUtils.getResourcesTypeInfo());
Assert.assertEquals(Resources.createResource(0, 3), res);
{code}
memory=20 should return 0 as it doesn't have a unit.
But YARN-5881 and YARN-7242 supports the API "memory=20" assuming MB is used by
default.
[~leftnoteasy], could you help to give some advice about how to use the memory
resource API.
Thanks a lot ~

> As the enum CapacitySchedulerConfiguration.AbsoluteResourceType only has two
> elements: memory and vcores, which would filter out absolute resources
> configuration of gpu and fpga in
> AbstractCSQueue.updateConfigurableResourceRequirement.
> This issue would cause gpu and fpga can't be allocated correctly
