    Description

      In this line, we are throwing UnknownHostException when any RM host can't resolve to ip address.
      https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/SecurityUtil.java#L448

      There are some cases that one RM needs to rename or map to different ip address, then it will crash the application although other RMs are running fine.
