    +This project is a wrapper around Hadoop's s3a file system. By pulling a smaller dependency
tree and
    +shading all dependencies away, this keeps the appearance of Flink being Hadoop-free,
    +from a dependency perspective.
    +We also relocate the shaded Hadoop version to allow running in a different
    +setup. For this to work, however, we needed to adapt Hadoop's `Configuration`
    +class to load a (shaded) `core-default-shaded.xml` configuration with the
    +relocated class names of classes loaded via reflection
    +(in the fute, we may need to extend this to `mapred-default.xml` and `hdfs-defaults.xml`
and their respective configuration classes).
