RestClient always gives “I/O reactor status: STOPPED”

[garry12]

I followed this thread but not able to resolve this issue I have a rest high level client and Elasticsearch 7.2 I am trying to bulk insert and keep getting this error -"java.lang.IllegalStateException: Request cannot be executed; I/O reactor status: STOPPED". Could anyone please help in getting me out of this?

Here I am pasting the code snippet of my actual code ...

public class ElasticSearchLoader
extends BaseLoader
{

private RestHighLevelClient client;
private BulkProcessor bulkProcessor;

private HashMap<String, ElasticFieldMapper> fieldMappers = new HashMap<String, ElasticFieldMapper>();

@Override
protected void performBegin() throws InitializeException
{
super.performBegin();

client = ElasticSearchHelper
    .makeConnection(clusterName.stringValue(), server.stringValue(), port.intValue());

BulkProcessor.Listener listener = new BulkProcessor.Listener() { 
   
    @Override
    public void afterBulk(long executionId, BulkRequest request,
            BulkResponse response) {
    	for (BulkItemResponse resp : response.getItems()) {
          if (resp.isFailed()) {
            System.out.println(resp.getFailureMessage());
            getResults().reportProblem(
                "Elastic Search Load Error",
                Severity.Error,
                resp.getFailureMessage(),
                null);

          }
        }
    }

    @Override
    public void afterBulk(long executionId, BulkRequest request,
            Throwable failure) {
    	  context.log().warn("Error loading bulk elastic search requests", failure);
    }


@Override
public void beforeBulk(long executionId, BulkRequest request) {
  context.log().info("Creating bulk processor.");
  context.log().info("Number of actions: " + request.numberOfActions());
}
};


 bulkProcessor = BulkProcessor.builder(
        (request, bulkListener) ->
            client.bulkAsync(request, RequestOptions.DEFAULT, bulkListener),
        listener).build();

BulkProcessor.Builder builder = BulkProcessor.builder(
        (request, bulkListener) ->
            client.bulkAsync(request, RequestOptions.DEFAULT, bulkListener),
        listener);


builder.setBulkActions(bulkActions.intValue()); 
builder.setBulkSize(new ByteSizeValue(bulkSize.intValue(), ByteSizeUnit.MB));
builder.setFlushInterval(TimeValue.timeValueSeconds(flushSeconds.intValue()));
builder.setConcurrentRequests(concurrentRequests.intValue()).build();
builder.setBackoffPolicy(
        BackoffPolicy.exponentialBackoff(TimeValue.timeValueMillis(100), 3));

setFieldMappers();

}

   // System.out.println("I am the E "+ name);

    Object value = field.getValueExpression().value(item);

    if (e.getType() != null) {

    builder.field(name, value);
