>                 Key: HDFS-15663
>                 URL: https://issues.apache.org/jira/browse/HDFS-15663
>             Project: Hadoop HDFS
>          Issue Type: Bug
>    Affects Versions: 3.3.0
>            Reporter: Chris Wensel
>            Priority: Major
>
> 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}}
