我想问一下目前是否可以使用 spark-ec2 脚本https://spark.apache.org/docs/latest/ec2-scripts.html以及不仅来自:aws_access_key_id和的凭据aws_secret_access_key，而且还包含aws_security_token.
当我尝试运行脚本时，我收到以下错误消息：
ERROR:boto:Caught exception reading instance data

有谁知道什么可能是错的？是aws_security_token问题吗？在我看来，这可能比 Spark 问题更像 boto。
我都试过了：
~/.aws/credentials1) 在和中设置凭据~/.aws/config
2）通过命令设置凭证：
export aws_access_key_id=<my_aws_access_key>
export aws_secret_access_key=<my_aws_seecret_key>
export aws_security_token=<my_aws_security_token>
我的启动命令是：
./spark-ec2 -k my_key -i my_key.pem --additional-tags "mytag:tag1,mytag2:tag2" --instance-profile-name "profile1" -s 1 launch test
