> The test {{TestTaskAttempt#testReducerCustomResourceType}} can occasionally fail with the following error:
> {noformat}
> org.apache.hadoop.yarn.exceptions.ResourceNotFoundException: Unknown resource 'a-custom-resource'. Known resources are [name: memory-mb, units: Mi, type: COUNTABLE, value: 0, minimum allocation: 0, maximum allocation: 9223372036854775807, name: vcores, units: , type: COUNTABLE, value: 0, minimum allocation: 0, maximum allocation: 9223372036854775807]

> at org.apache.hadoop.mapreduce.v2.app.job.impl.TestTaskAttempt.testReducerCustomResourceTypes(TestTaskAttempt.java:1535)
> {noformat}
> The root cause seems to be an interference from previous tests that start instance(s) of {{FailingAttemptsMRApp}} or {{FailingAttemptsDuringAssignedMRApp}}. When I disabled these tests, {{testReducerCustomResourceTypes}} always passed.
