我无法在Amazon Web Service（我在Windows计算机上）上启动Spark集群。我对Spark，Linux或AWS知之甚少，所以我一直遵循https://www.safaribooksonline.com/videos/using-r-for/9781491973035/9781491973035-video283162上的分步指南。
到目前为止，我已经设法使用腻子连接到AWS，并在spark，github等站点下载/解压缩/安装了相关文件。这是我的腻子窗口中的目录：

我还运行了“ aws configure”并输入了正确的访问密钥：
[ec2-user@ip-10-0-0-235 spark-ec2]$ aws configure
AWS Access Key ID [****************DL5A]:
AWS Secret Access Key [****************KCQ5]:
Default region name [us-east-2]:
Default output format [None]:
[ec2-user@ip-10-0-0-235 spark-ec2]$
这是哪里出了问题。我被告知应该输入以下命令：
./spark-ec2 -k Spark3 -i /home/ec2-user/Spark3.pem -s 1 -t t2.large -r
us-east-2 -z us-east-2a launch my_clusters
，这将开始设置过程，该过程需要几分钟。但是我立即收到以下错误消息：
[ec2-user@ip-10-0-0-235 spark-ec2]$ ./spark-ec2 -k Spark3 -i /home/ec2-
user/Spark3.pem -s 1 -t t2.large -r us-east-2 -z us-east-2a launch

我尝试了几种不同的方法，它们都给出了不同的错误消息。首先，我在它前面加上“ sudo”，然后得到它：
[ec2-user@ip-10-0-0-235 spark-ec2]$ sudo ./spark-ec2 -k Spark3 -i
/home/ec2-user/Spark3.pem -s 1 -t t2.large -r us-east-2 -z us-east-2a
launch my_clusters
ERROR: The environment variable AWS_ACCESS_KEY_ID must be set
[ec2-user@ip-10-0-0-235 spark-ec2]$
这很奇怪，因为我在运行“ aws configure”时设置了AWS访问密钥。但是我还是尝试手动设置它，我得到了：
[ec2-user@ip-10-0-0-235 spark-ec2]$ set
AWS_ACCESS_KEY_ID=AKIAI624LY4HBRFIDL5A
[ec2-user@ip-10-0-0-235 spark-ec2]$ sudo ./spark-ec2 -k Spark3 -i
/home/ec2-user/Spark3.pem -s 1 -t t2.large -r us-east-2 -z us-east-2a
launch my_clusters
ERROR: The environment variable AWS_ACCESS_KEY_ID must be set
[ec2-user@ip-10-0-0-235 spark-ec2]$ $ export
AWS_ACCESS_KEY_ID=AKIAI624LY4HBRFIDL5A
-bash: $: command not found
[ec2-user@ip-10-0-0-235 spark-ec2]$ sudo ./spark-ec2 -k Spark3 -i
/home/ec2-user/Spark3.pem -s 1 -t t2.large -r us-east-2 -z us-east-2a
launch my_clusters
ERROR: The environment variable AWS_ACCESS_KEY_ID must be set
[ec2-user@ip-10-0-0-235 spark-ec2]$
因此，无论我做什么，似乎都无法识别AWS访问密钥。最后，我尝试在命令中保留一些选项，然后我得到了：
[ec2-user@ip-10-0-0-235 spark-ec2]$ ./spark-ec2 -k Spark3 -i /home/ec2-
user/Spark3.pem -s 1 launch my_clusters

所以我真的不知道该怎么办。在教学视频中，它运行得非常好，对于这些特定的错误消息，我无法在线找到任何帮助。
任何帮助将不胜感激。
