[BUG] Shape property doesn't work, should be XyShape

[grouh]

What is the bug?

When using the shape property with the opensearch java client, this result as an error as it is known to OpenSearch, where this feature has the name xy_shape

How can one reproduce the bug?

In OpenSearch

{
  "mappings": {
    "properties": {
      "myshapeprop": {
        "type": "shape"
      }
    }
  }
}

Will result in the following error

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "No handler for type [shape] declared on field [myshapeprop]"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [_doc]: No handler for type [shape] declared on field [myshapeprop]",
    "caused_by": {
      "type": "mapper_parsing_exception",
      "reason": "No handler for type [shape] declared on field [myshapeprop]"
    }
  },
  "status": 400
}

When using the xy_shape property, it works properly

PUT index_with_shape
{
  "mappings": {
    "properties": {
      "myshapeprop": {
        "type": "xy_shape"
      }
    }
  }
}

Will get

{
  "acknowledged": true,
  "shards_acknowledged": true,
  "index": "index_with_shape"
}

This due to Shape Elasticearch Feature
being implemented as XY Shape in Opensearch

When using the Opensearch Java client

// opensearchClient is injected through a bean
String templateMapping = "{"properties":{"myshapeprop": {"type": "xy_shape"}}}";
JsonpMapper mapper = opensearchClient._transport().jsonpMapper();
JsonParser mappingsParser =
      mapper
        .jsonProvider()
        .createParser(new StringReader(templateMapping));

TypeMapping typeMapping = TypeMapping._DESERIALIZER.deserialize(mappingsParser, mapper);

return CreateIndexRequest.Builder()
      .mappings(typeMapping)
      .build();

Will result in the following error

[org.opensearch.client.util.MissingRequiredPropertyException - Missing required property 'Builder.<variant kind>']

What is the expected behavior?

Expected behavior is for Index to be created with the xy_shape property

What is your host/environment?

Tested with

• a docker environment with opensearchproject/opensearch:2.11.1
• Library opensearch-java in version 2.9.0
