             Summary: YARN Service Client does not work with SPNEGO when knox is configured
                 Key: YARN-9334
                 URL: https://issues.apache.org/jira/browse/YARN-9334
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn-native-services
    Affects Versions: 3.2.0, 3.1.0
            Reporter: Tarun Parimi


When knox is configured, the configuration hadoop.http.authentication.type is set to org.apache.hadoop.security.authentication.server.JWTRedirectAuthenticationHandler instead of kerberos.

We have the following check in ApiServiceClient#getApiClient for kerberos.
{code:java}
if (conf.get("hadoop.http.authentication.type").equals("kerberos")) {
      try {
        URI url = new URI(requestPath);
        String challenge = YarnClientUtils.generateToken(url.getHost());
        builder.header(HttpHeaders.AUTHORIZATION, "Negotiate " + challenge);
      } catch (Exception e) {
        throw new IOException(e);
      }
    }
{code}

So we always get 401 error since there is no auth handled for knox.
