flink 1.3.1 elasticsearch 5.5.1. ElasticsearchSinkFunction fails with java.lang.NoSuchMethodError

Question

I'm going through following samples using Scala / sbt:

flink / elasticsearch / kibana
flink tutorial

My built.sbt includes following versions:

libraryDependencies ++= Seq(
  "org.apache.flink" %% "flink-scala" % "1.3.1" % "provided",
  "org.apache.flink" %% "flink-streaming-scala" % "1.3.1" % "provided",
  "org.apache.flink" %% "flink-clients" % "1.3.1" % "provided",
  "joda-time" % "joda-time" % "2.9.9",
  "com.google.guava" % "guava" % "22.0",
  "com.typesafe" % "config" % "1.3.0",
  "org.apache.flink" % "flink-connector-kafka-0.10_2.10" % "1.2.0",
  "org.elasticsearch" % "elasticsearch" % "5.5.1",
  "org.elasticsearch.client" % "transport" % "5.5.1",
  "org.apache.flink" % "flink-connector-elasticsearch5_2.10" % "1.3.1"
)

Program fails with following exception (substract):

Here are my related imports:

import org.apache.flink.streaming.connectors.elasticsearch5.ElasticsearchSink
import org.apache.flink.streaming.connectors.elasticsearch.{ElasticsearchSinkFunction, RequestIndexer}
import org.elasticsearch.action.index.IndexRequest
import org.elasticsearch.client.Requests

Here is code for MyElasticsearchInserter:

  final class MyElasticsearchInserter(index: String, mappingType: String)
    extends ElasticsearchSinkFunction[(Int, Long, (Float, Float), Short)] {

    def process(element: (Int, Long, (Float, Float), Short),
                ctx: RuntimeContext,
                indexer: RequestIndexer): Unit = {

      // construct JSON document to index
      val json = Map(
        "time" -> element._2.toString,
        "location" -> (element._3._1 + "," + element._3._2),
        "cnt" -> element._4.toString
      )

      val rqst: IndexRequest = Requests.indexRequest
        .index(index)
        .`type`(mappingType)
        .source(json.asJava)
      indexer.add(rqst)
    }
  }

Here is code for adding a Sink:

if (writeToElasticsearch) {
  // write to Elasticsearch
  nycRides.addSink(new ElasticsearchSink(esConfig,
    esTransport, new MyElasticsearchInserter("nyc-idx", "popular-locations")))

}

It looks the question is rather if flink 1.3.1 can be used with elasticsearch 5.5.1? Following method is not found?

Caused by: java.lang.NoSuchMethodError: org.elasticsearch.action.bulk.BulkProcessor.add(Lorg/elasticsearch/action/ActionRequest;)Lorg/elasticsearch/action/bulk/BulkProcessor;
        at org.apache.flink.streaming.connectors.elasticsearch.BulkProcessorIndexer.add(BulkProcessorIndexer.java:52)

Thanks a lot

Answer 1

Just after a quick look at ES code base I think they removed that method(BulkProcessor#add(ActionRequest)) in 5.2.0.

Flink uses that method internally. Unfortunately I fear Flink connector won't work with ES 5.3+ connector right now.
