Steve Loughran commented on HADOOP-17337:
-----------------------------------------
Checking up on this. I'd like to make this a blocker for 3.3.1, as it is bad
news for lightweight docker deployments.
# [~cwensel] do you know anyone who can work on this
# what do people think would be the way to do it?
I'm thinking we'd need a PatchTheSocketFactory interface, try to load an
implementation which does this to the shaded one; if that doesn't load fall
back to one to patch the unshaded one. That way even unshaded aws-s3 libraries
would be able to switch to openssl

> 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
> Fix For: 3.3.1
>
>
> 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:
