Flink Elastic Search Sink Type Mismatch error












0















I'm connecting Flink and Elastic Search. With the help of documentation. I created a sink using Scala.



def getEsSink:ElasticsearchSink[CustomerSegementation] = {
val httpHosts = new util.ArrayList[HttpHost]
httpHosts.add(new HttpHost("10.0.35.148", 9200, "http"))
val esSinkBuilder = new ElasticsearchSink.Builder[CustomerSegementation](httpHosts, new ElasticsearchSinkFunction[CustomerSegementation]() {
def createIndexRequest(element: CustomerSegementation): IndexRequest = {
val json = new java.util.HashMap[String, String]
json.put("_id", element._id)
json.put("last_ordered_date", element.last_ordered_date.toString)
Requests.indexRequest.index("customerSegementation").`type`("test_type").source(json)
}

@Override
def process(element: CustomerSegementation, ctx: RuntimeContext, indexer: RequestIndexer): Unit = {
indexer.add(createIndexRequest(element))
}
})
esSinkBuilder.setBulkFlushMaxActions(1)
esSinkBuilder.build()
}


Then I am trying to add the sink to the stream



stream.addSink(getEsSink())


I get error saying
enter image description here



I'm not sure where I'm exactly going wrong. I'm using Flink version 1.6.0 and ElasticSearch version 6 and Scala version 2.11.



Please help me.

    Check the element type from stream. Looks like the type from stream is ObjectNode, which does not match with CustomerSegmentation.
