Steve Loughran commented on HADOOP-12420:
-----------------------------------------
OK, this looks likes an AWS library version change, the one handled in
HADOOP-12269
Summary: Hadoop 2.7.1 needs aws-java-sdk version 1.7.4; the aws release,
aws-java-sdk-s3 v 1.10.6 has changed the signature and doesn't work.
Right now there's not a lot we can do except wait for people to type in the
stack trace into their browser and end up here; for 2.7.2 we could think about
backporting the library change.

> 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
