Steve Loughran resolved HADOOP-12420.
-------------------------------------
       Resolution: Fixed
    Fix Version/s: 2.8.0

Marking as fixed for Hadoop 2.8, the library change fixes that. If you see it in earlier versions, you've got an incompatible version of aws-java-sdk, as Amazon have broken their java method signature

> While trying to access data stored in Amazon S3 through Apache Spark, which  internally uses hadoop-aws jar I was getting the following exception :
> Exception in thread "main" java.lang.NoSuchMethodError: com.amazonaws.services.s3.transfer.TransferManagerConfiguration.setMultipartUploadThreshold(I)V
> Probable reason could be the fact that aws java sdk expects a long parameter for the setMultipartUploadThreshold(long multiPartThreshold) method, but hadoop-aws was using a parameter of type int(multiPartThreshold). 
> I tried using the downloaded hadoop-aws jar and the build through its maven dependency, but in both the cases I encountered the same exception. Although I can see private long multiPartThreshold; in hadoop-aws GitHub repo, it's not getting reflected in the downloaded jar or in the jar created from maven dependency.
> Following lines in the S3AFileSystem class create this difference :
> Build from trunk : 
> private long multiPartThreshold;
> this.multiPartThreshold = conf.getLong("fs.s3a.multipart.threshold", 2147483647L); => Line 267
> Build through maven dependency : 
> private int multiPartThreshold;
> multiPartThreshold = conf.getInt(MIN_MULTIPART_THRESHOLD, DEFAULT_MIN_MULTIPART_THRESHOLD); => Line 249
