### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened when RM HA is enabled，set yarnHaIps="hadoop01,hadoop02", if thadoop01 is down，ds can't get the active RM correctly, i think this is a bug in 2.0.0 and 1.3.9, method getAcitveRMName in 1.3.9 ``` public static String getAcitveRMName(String rmIds) { String[] rmIdArr = rmIds.split(Constants.COMMA); int activeResourceManagerPort = PropertyUtils.getInt(Constants.HADOOP_RESOURCE_MANAGER_HTTPADDRESS_PORT, 8088); String yarnUrl = "http://%s:"; + activeResourceManagerPort + "/ws/v1/cluster/info"; String state = null; try { /** * send http get request to rm1 */ state = getRMState(String.format(yarnUrl, rmIdArr[0])); if (Constants.HADOOP_RM_STATE_ACTIVE.equals(state)) { return rmIdArr[0]; } else if (Constants.HADOOP_RM_STATE_STANDBY.equals(state)) { state = getRMState(String.format(yarnUrl, rmIdArr[1])); if (Constants.HADOOP_RM_STATE_ACTIVE.equals(state)) { return rmIdArr[1]; } } else { return null; } } catch (Exception e) { state = getRMState(String.format(yarnUrl, rmIdArr[1])); if (Constants.HADOOP_RM_STATE_ACTIVE.equals(state)) { return rmIdArr[0]; } } return null; } ``` methos getAcitveRMName in 2.0.0 ``` public static String getAcitveRMName(String rmIds) { String[] rmIdArr = rmIds.split(Constants.COMMA); int activeResourceManagerPort = PropertyUtils.getInt(Constants.HADOOP_RESOURCE_MANAGER_HTTPADDRESS_PORT, 8088); String yarnUrl = "http://%s:"; + activeResourceManagerPort + "/ws/v1/cluster/info"; try { /** * send http get request to rm */ for (String rmId : rmIdArr) { String state = getRMState(String.format(yarnUrl, rmId)); if (Constants.HADOOP_RM_STATE_ACTIVE.equals(state)) { return rmId; } } } catch (Exception e) { logger.error("yarn ha application url generation failed, message:{}", e.getMessage()); } return null; } ``` ### What you expected to happen when RM HA is enabled，i think ds should get active RM correctly ，as long as one RM works，even when all the others are down . ### How to reproduce when RM HA is enabled，set yarnHaIps="hadoop01,hadoop02", make thadoop01 down，ds can't get the active RM correctly。 ### Anything else _No response_ ### Version 2.0.0 ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
