Spark read s3 using sc.textFile("s3a://bucket/filePath"). java.lang.NoSuchMethodError: com.amazonaws.services.s3.transfer.TransferManager

Question

I have add blew jars to spark/jars path.

• hadoop-aws-2.7.3.jar
• aws-java-sdk-s3-1.11.126.jar
• aws-java-sdk-core-1.11.126.jar
• spark-2.1.0

In spark-shell

scala> sc.hadoopConfiguration.set("fs.s3a.access.key", "***")

scala> sc.hadoopConfiguration.set("fs.s3a.secret.key", "***")

scala> val f = sc.textFile("s3a://bucket/README.md")

scala> f.count

1. "java.lang.NoSuchMethodError: com.amazonaws.services.s3.transfer.TransferManager" is raised by mismatched jar? (hadoop-aws, aws-java-sdk)

2. To access data stored in Amazon S3 from Spark applications should use Hadoop file APIs. So is hadoop-aws.jar contains the Hadoop file APIS or must run hadoop env ?

Answer 1

Mismatched JARs; the AWS SDK is pretty brittle across versions.

Hadoop S3A code is in hadoop-aws JAR; also needs hadoop-common. Hadoop 2.7 is built against AWS S3 SDK 1.10.6. (*updated: No, it's 1.7.4. The move to 1.10.6 went into Hadoop 2.8)HADOOP-12269

You must use that version. If you want to use The 1.11 JARs then you will need to check out the hadoop source tree and build branch-2 yourself. The good news: that uses the shaded AWS SDK so its versions of jackson and joda time don't break things. Oh, and if you check out spark master, and build with the -Phadoop-cloud profile, it pulls the right stuff in to set Spark's dependencies up right.

Update: Oct 1 2017: Hadoop 2.9.0-alpha and 3.0-beta-1 use 1.11.199; assume the shipping versions will be that or more recent.
