Exception during create index operation using java high level rest client

Elastic Stack Elasticsearch

Hi,

I am using java high level rest client v6.2.2 to connect es cluster v5.3.1. The create index api creates the index successfully but throws the exception:

Exception in thread "main" java.io.IOException: Unable to parse response body for Response{requestLine=PUT /<my index name>?master_timeout=30s&timeout=30s HTTP/1.1, host=cluster host, response=HTTP/1.1 200 OK}

	at org.elasticsearch.client.RestHighLevelClient.performRequest(RestHighLevelClient.java:505)
	... 4 more

I have the following code:

CreateIndexRequest request     = new CreateIndexRequest(index);
request.source(SCHEMA_JSON, XContentType.JSON);
CreateIndexResponse createIndexResponse = esRestHighLevelClient.indices().create(request);

SCHEMA_JSON : contains mapping, index settings etc.

Am I doing something wrong?

Thanks in advance for your help.

Best,
Ashutosh

I am using java high level rest client v6.2.2 to connect es cluster v5.3.1.

That's the problem.

Sadly the 6.x client is not fully compatible with 5.x.

Tanks David for your reply. It seems I miss understood the compatibility staff between low-level and high-level rest client.

Best,
