Gera Shegalov created YARN-3568:
-----------------------------------

             Summary: TestAMRMTokens should use some random port
                 Key: YARN-3568
                 URL: https://issues.apache.org/jira/browse/YARN-3568
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.8.0
            Reporter: Gera Shegalov


Since the default port is used for yarn.resourcemanager.scheduler.address, if we already run a pseudo-distributed cluster on the same development machine, the test fails like this:
