Tinkerpop Gremlin控制台：java.lang.NoSuchMethodError：org.apache.tinkerpop.gremlin.driver.RequestOptions $ Builder.userAgent [英] Tinkerpop Gremlin Console: java.lang.NoSuchMethodError: org.apache.tinkerpop.gremlin.driver.RequestOptions$Builder.userAgent

问题描述

作为我在> 403中针对Gremlin到AWS Neptune的禁止错误，我可以通过安装在EC2实例上的Tinkerpop Gremlin控制台v 3.4.3（如 https://docs.aws.amazon.com/neptune/latest/userguide/iam-auth- connection-gremlin-console.html 不适用于我。

但是，我在控制台上使用的所有Gremlin命令（g。）都出现NoSuchMethodError错误。

例如：

解决方案
我认为您缺少的步骤是采用EC2实例分配的IAM角色提供的临时凭据，并且将它们推送到默认凭据提供程序链中，以使它们可以被Gremlin Console使用的SigV4Channelizer看到。可以在此处查看该过程的高级概述： https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/setup-credentials.html  
 
 
 
可以在此处找到针对海王星的更规范的处理方式： https://docs.aws.amazon.com/neptune/latest/userguide/iam-auth-temporary-credentials.html 请参阅标题为为Neptune IAM设置Amazon EC2的部分身份验证。
 
As my last post at 403 Forbidden error for Gremlin to AWS Neptune, I could successfully connect to my Neptune Cluster DB via my Tinkerpop Gremlin console v 3.4.3 that installed at my EC2 instance as v 3.4.1 suggested at https://docs.aws.amazon.com/neptune/latest/userguide/iam-auth-connecting-gremlin-console.html didn't work for me.

However, I'm getting NoSuchMethodError error for all Gremlin commands (g.) that I used on the console.

e.g: 
g.V()

I have also tried the latest Apache Tinkerpop Gremlin Console 3.4.6, same error I had...

Thanks

I think the step you're missing is taking the temporary credentials provided by your EC2 instance's assigned IAM role and pushing those into the Default Credential Provider chain in order for them to be seen by the SigV4Channelizer used by the Gremlin Console.  A high level overview of that process can be seen here:  https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/setup-credentials.html

A more prescriptive way of handling this for Neptune can be found here:  https://docs.aws.amazon.com/neptune/latest/userguide/iam-auth-temporary-credentials.html  See the section titled, "Setting Up Amazon EC2 for Neptune IAM Authentication".
