Description

Yarn Client uses local address instead of RM address as token renewer in a secure cluster when RM HA is enabled. This will cause HDFS token renew failure for renewer "nobody" if the rules from hadoop.security.auth_to_local exclude the client address in HDFS DelegationTokenIdentifier.
The reason why the local address is returned is: When HA is enabled, "yarn.resourcemanager.address" may not be set, if HOSTNAME_PATTERN("_HOST") is used in "yarn.resourcemanager.principal", the default address "0.0.0.0:8032" will be used, Based on the following code at SecurityUtil.java, the local address will be used to replace "0.0.0.0".

  private static String replacePattern(String[] components, String hostname)
      throws IOException {
    String fqdn = hostname;
    if (fqdn == null || fqdn.isEmpty() || fqdn.equals("0.0.0.0")) {
      fqdn = getLocalHostName();
    }
    return components[0] + "/" + fqdn.toLowerCase(Locale.US) + "@" + components[2];
  }
  static String getLocalHostName() throws UnknownHostException {
    return InetAddress.getLocalHost().getCanonicalHostName();
  }
  public static String getServerPrincipal(String principalConfig,
      InetAddress addr) throws IOException {
    String[] components = getComponents(principalConfig);
    if (components == null || components.length != 3
        || !components[1].equals(HOSTNAME_PATTERN)) {
      return principalConfig;
    } else {
      if (addr == null) {
        throw new IOException("Can't replace " + HOSTNAME_PATTERN
            + " pattern since client address is null");
      }
      return replacePattern(components, addr.getCanonicalHostName());
    }
  }

The following is the exception which cause the job fail:
