I am using spark 1.6.0 in a cluster created using the spark-ec2 script. I am using the standalone cluster manager
My java streaming app is not able to write to s3. It appears to be some for of permission problem. Any idea what the problem might be? I tried use the IAM simulator to test the policy. Everything seems okay. Any idea how I can debug this problem? Thanks in advance Andy JavaSparkContext jsc = new JavaSparkContext(conf); // I did not include the full key in my email // the keys do not contain \¹ // these are the keys used to create the cluster. They belong to the IAM user andy jsc.hadoopConfiguration().set("fs.s3n.awsAccessKeyId", "AKIAJREX"); jsc.hadoopConfiguration().set("fs.s3n.awsSecretAccessKey", "uBh9v1hdUctI23uvq9qR"); private static void saveTweets(JavaDStream<String> jsonTweets, String outputURI) { jsonTweets.foreachRDD(new VoidFunction2<JavaRDD<String>, Time>() { private static final long serialVersionUID = 1L; @Override public void call(JavaRDD<String> rdd, Time time) throws Exception { if(!rdd.isEmpty()) { // bucket name is com.pws.twitter¹ it has a folder json' String dirPath = "s3n://s3-us-west-1.amazonaws.com/com.pws.twitter/json² + "-" + time.milliseconds(); rdd.saveAsTextFile(dirPath); } } }); Bucket name : com.pws.titter Bucket policy (I replaced the account id) { "Version": "2012-10-17", "Id": "Policy1455148808376", "Statement": [ { "Sid": "Stmt1455148797805", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::123456789012:user/andy" }, "Action": "s3:*", "Resource": "arn:aws:s3:::com.pws.twitter/*" } ] }
