Jonathan Eagles commented on TEZ-2097:
--------------------------------------

WebAppUtils is listed as private/evolving. With that in mind should I move that 
functionality to Tez until WebAppUtils is public?

  public static String getRunningLogURL(
      String nodeHttpAddress, String containerId, String user) {
    if (nodeHttpAddress == null || nodeHttpAddress.isEmpty() ||
        containerId == null || containerId.isEmpty() ||
        user == null || user.isEmpty()) {
      return null;
    }
    return PATH_JOINER.join(
        nodeHttpAddress, "node", "containerlogs", containerId, user);
  }
