How to use

lastErrorPath

method

in

org.apache.storm.cluster.ClusterUtils

@Override
public ErrorInfo lastError(String stormId, String componentId) {
  String path = ClusterUtils.lastErrorPath(stormId, componentId);
  if (stateStorage.node_exists(path, false)) {
    ErrorInfo errorInfo = ClusterUtils.maybeDeserialize(stateStorage.get_data(path, false), ErrorInfo.class);
    return errorInfo;
  }
  return null;
}

@Override
public void reportError(String stormId, String componentId, String node, Long port, Throwable error) {
  String path = ClusterUtils.errorPath(stormId, componentId);
  String lastErrorPath = ClusterUtils.lastErrorPath(stormId, componentId);
  ErrorInfo errorInfo = new ErrorInfo(ClusterUtils.stringifyError(error), Time.currentTimeSecs());
  errorInfo.set_host(node);
