             Summary: While trying to access Amazon S3 through hadoop-aws(Spark basically) I was getting Exception in thread "main" java.lang.NoSuchMethodError: com.amazonaws.services.s3.transfer.TransferManagerConfiguration.setMultipartUploadThreshold(I)V
                 Key: HADOOP-12420
                 URL: https://issues.apache.org/jira/browse/HADOOP-12420
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/s3
    Affects Versions: 2.7.1
            Reporter: Tariq Mohammad
            Assignee: Tariq Mohammad
            Priority: Minor


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
