Hello, I was working on ES - hadoop connector and I see that if you server has less memory writes keep on getting dropped. org.elasticsearch.hadoop.EsHadoopException: Could not write all entries (maybe ES was overloaded?). Bailing out... As mentioned in [Pushback to hadoop from es on bulk load](https://discuss.elastic.co/t/pushback-to-hadoop-from-es-on-bulk-load/1535/5) there's no bi-directional communication between Hadoop and the connector - the connector cannot say, there's too much data, slow down. Does anyone think it might be a good idea to use sth. like Blocking Queues here and add acks while writing (kafka 101) 🙂 so as to let the consumer (thread on ES) read at slower pace. Else we would have to tune the batch size, write speed, http timeouts ourself. I'm open to building/contributing to this its a good idea. ---

I like the idea! ---
