我正在尝试在Hadoop 3.1.2中使用s3proxy，但出现403错误，而在hadoop 2.7中它似乎可以工作。这是我的回归还是配置错误？
s3proxy配置
s3proxy.endpoint=http://127.0.0.1:4242
s3proxy.authorization=aws-v2
s3proxy.identity=local-identity
s3proxy.credential=local-credential
jclouds.provider=filesystem
jclouds.filesystem.basedir=/tmp/s3proxy
简单的scala代码
sc.hadoopConfiguration.set("fs.s3a.impl", "org.apache.hadoop.fs.s3a.S3AFileSystem")
sc.hadoopConfiguration.set("fs.s3a.aws.credentials.provider", "org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider")
sc.hadoopConfiguration.set("fs.s3a.endpoint", "127.0.0.1:4242")
sc.hadoopConfiguration.set("fs.s3a.connection.ssl.enabled", "false")
sc.hadoopConfiguration.set("fs.s3a.access.key", "local-identity")
sc.hadoopConfiguration.set("fs.s3a.secret.key", "local-credential")
val rdd = sc.textFile("s3a://wiki/test.json")
rdd.collect().foreach(println)
与
tree /tmp/s3proxy/tmp/s3proxy/
└── wiki
└── test.json
使用hadoop2.7，可以获得正确的输出。
cat demo_wiki/test01.scala | ./spark-2.4.4-bin-hadoop2.7/bin/spark-shell --jars hadoop-aws-2.7.3.jar,aws-java-sdk-1.7.4.jar
但是使用hadoop3.1.2，我收到403错误。
cat demo_wiki/test01.scala | ./spark-2.4.4-bin-hadoop3.1/bin/spark-shell --jars hadoop-aws-3.1.2.jar,aws-java-sdk-bundle-1.11.271.jar
输出:
2019-09-23 15:23:32 WARN MetricsConfig:134 - Cannot locate configuration: tried hadoop-metrics2-s3a-file-system.properties,hadoop-metrics2.properties
java.nio.file.AccessDeniedException: s3a://wiki/test.json: getFileStatus on s3a://wiki/test.json: com.amazonaws.services.s3.model.AmazonS3Exception: Forbidden (Service: Amazon S3; Status Code: 403; Error Code: 403 Forbidden; Request ID: 4442587FB7D0A2F9; S3 Extended Request ID: null), S3 Extended Request ID: null:403 Forbidden
任何的想法 ？
最佳答案
找到了看Dockerfile(https://github.com/gaul/s3proxy/blob/master/Dockerfile#L24)的答案
正确的s3proxy配置是
s3proxy.endpoint=http://127.0.0.1:4242
s3proxy.authorization=aws-v2-or-v4
s3proxy.identity=local-identity
s3proxy.credential=local-credential
jclouds.provider=filesystem
jclouds.filesystem.basedir=/tmp/s3proxy
并且具有最新(当时)版本的spark-2.4.4 + hadoop-3.2.0 + aws-sdk-1.11.636的命令行运行正常
cat test.scala | ./spark-2.4.4-bin-hadoop3.2/bin/spark-shell --jars hadoop-aws-3.2.0.jar,aws-java-sdk-bundle-1.11.636.jar
