    Description

      From https://builds.apache.org/job/PreCommit-YARN-Build/9661/artifact/patchprocess/patch-unit-hadoop-yarn-project_hadoop-yarn_hadoop-yarn-client-jdk1.7.0_79.txt, we can see the tests in TestYarnClient, TestAMRMClient and TestNMClient get timeout which can be reproduced locally.

      When /etc/hosts has multiple loopback entries, InetAddress.getByName(null) will be returning the first entry present in etc/hosts. Hence its possible that machine hostname can be second in list and cause UnKnownHostException.

      Suggesting a direct resolve for such hostname scenarios.
