> Key: HADOOP-17337
> URL: https://issues.apache.org/jira/browse/HADOOP-17337
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Chris Wensel
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 3.3.1
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The hadoop-aws library has a dependency on
> 'com.amazonaws':aws-java-sdk-bundle' which in turn is a fat jar of all AWS
> SDK libraries and shaded dependencies.
>
> This dependency is 181MB.
>
> Some applications using the S3AFilesystem may be sensitive to having a large
> footprint. For example, building an application using Parquet and bundled
> with Docker.
>
> Typically, in prior Hadoop versions, the bundle was replaced by the specific
> AWS SDK dependencies, dropping the overall footprint.
>
> In 3.3 (and maybe prior versions) this strategy does not work because of the
> following exception:
> {{java.lang.NoClassDefFoundError:
> com/amazonaws/thirdparty/apache/http/conn/socket/ConnectionSocketFactory}}
