我很难从一个轻率的工作中获得S3。
如果我提交组装好的jar用于我的工作,我会得到一个拒绝访问错误:
Caused by:
com.amazon.ws.emr.hadoop.fs.shaded.com.amazonaws.services.s3.model.AmazonS3Exception:
Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: ...; S3 Extended Request ID: ...), S3 Extended Request ID: ...
这是我的设置:
的EMR群集是用“高级配置”创建的,
燧石1.4.0。和Hadoop 2.8.3。作为应用程序。
1X主节点,2X节点
实例具有
EMR_EC2_DefaultRole
具有策略AmazonePlasticMapReduceforeC2角色,具有S3完全访问权限。
实际上,我可以在主节点和从节点上成功地发出这些命令:
aws s3api list-buckets
hdfs dfs -ls s3://bucketA
我连接到主机并启动群集:
/usr/lib/flink/bin/yarn-session.sh -n 2 -d
Flink作业从桶中读取源代码:
object TestS3 {
def main(args: Array[String]): Unit = {
val env: ExecutionEnvironment = ExecutionEnvironment.getExecutionEnvironment
val input: DataSet[String] = env.readTextFile("s3://bucketA/source/file")
input.writeAsText("s3://bucketB/delete/me/later")
env.execute()
}
}
这是我的Simple Build.sbt:
name := "TestS3"
scalaVersion := "2.11.11"
version := "0.1"
val flinkVersion = "1.4.0"
libraryDependencies ++= Seq(
"org.apache.flink" % "flink-core" % flinkVersion % "provided",
"org.apache.flink" %% "flink-scala" % flinkVersion % "provided"
)
该存储桶没有拒绝读取访问的策略。它有拒绝删除的策略,但这不会影响Flink作业。
这个
EMR_EC2_Default_Role
允许完全访问S3。
像往常一样,任何我做错了什么的暗示都是非常感激的。或者我的期望是错误的?!
这是完整的stacktrace:
