Why do we need dynamodb?

[scott-routledge2]

I'm not sure, I saw the error after adding s3.

I'll investigate a bit more.

[scott-routledge2]

From the error, it looks like dynamo might be a dependency of hadoop.fs.s3a.S3AFileSystem.

And we are seeing these errors in the first place because we are explicitly excluding the aws-java-sdk-bundled dependency--

I am assuming this is to keep our JAR size small?

[IsaacWarren]

Yeah it's for jar size
