issues with swagger.json API

["lexaneon@gmail.com" <le...@gmail.com>]

Hello,

I would like to share my experience of using API which is generated against swagger json (http://atlas.apache.org/api/v2/ui/index.html#!/TypesREST/getTypeDefByName <http://atlas.apache.org/api/v2/ui/index.html#!/TypesREST/getTypeDefByName>    json: http://atlas.apache.org/api/v2/ui/swagger.json) and hope that you can get me any suggestions.
in swagger.json <http://atlas.apache.org/api/v2/ui/swagger.json> there is no legs which are responsible for security, that is why when creating instance of ApiClient  and set user name\password there is problem like this <https://github.com/swagger-api/swagger-codegen/issues/1054> - ApiClient.setUsername throw exception "No HTTP basic authentication configured!"

 (swagger is not add auth methods to ApiClient constructor, it looks like:
public ApiClient() {
    httpClient = new OkHttpClient();

    verifyingSsl = true;

    json = new JSON();

    // Set default User-Agent.
    setUserAgent("Swagger-Codegen/1.0.0/java");

    // Setup authentications (key: authentication name, value: authentication).
    authentications = new HashMap<String, Authentication>();
    // Prevent the authentications from being modified.
    authentications = Collections.unmodifiableMap(authentications);
}
I've resolved this issue - just added next fields to swagger.json and regenerate java-class through codegen
"security": {
      "basicAuth": []
  },
  "securityDefinitions": {
    "basicAuth":{
      "type": "basic"
    }
  },

Pls. fix this issue in your swagger.json tamplate or say where I can find correct one.

2. I tried use TypesRestApi.getTypeDefByName(“hive_table”)
but there is one more issue:

Exception in thread "main" java.lang.IllegalArgumentException: missing discriminator field: <>

and at this step I don’t know how I can fix this.
I would grateful if you send me example how I should use it or just point on me mistakes.

here is my code for #2
import java.util.Base64

import io.swagger.client.{ApiClient}
import io.swagger.client.api.TypesRestApi
import org.apache.http._

object SwaggerApiTest extends App{

  val apiClient = new ApiClient()
  val (atlasUsename, atalsPassword) = ("admin", "admin")
  val connectStr = "Basic " + new String(Base64.getEncoder.encode((atlasUsename + ":" + atalsPassword).getBytes))
  apiClient.setBasePath("http://localhost:21000/api/atlas")
  apiClient.addDefaultHeader(HttpHeaders.AUTHORIZATION, connectStr)
  val typesRestApi = new TypesRestApi(apiClient)
  apiClient.setDebugging(true)
//  testGetTypesDef()
  getTypeDefByName("hive_table")

  def testGetTypesDef() ={
    val listTypeDefDeaders = typesRestApi.getTypeDefHeaders

    listTypeDefDeaders.forEach(x => println(x.getName()))
  }
  def getTypeDefByName(typeDefName: String)={

    val typeDef = typesRestApi.getTypeDefByName(typeDefName)
    typeDef

  }

}
I look forward to hearing from you in the nearest future.

Kind regards,
Aleksey.
