The name is confusing because most Java classes prefixed with "Abstract" is
actually defined as an abstract class rather than interface.
Maybe change it to just HadoopWrapper instead.
> Generalize Flink's DistributedFileSystemClass to a Hadoop FileSystem wrapper
> ----------------------------------------------------------------------------

> Key: FLINK-1266
> URL: https://issues.apache.org/jira/browse/FLINK-1266
> Project: Flink
> Issue Type: Improvement
> Reporter: Robert Metzger
> Assignee: Robert Metzger
> Priority: Minor
>
> Currently, the Hadoop's DistributedFileSystem class is somewhat hardwired
> into the Flink DistributedFileSystem class.
> That is actually not necessary because Flink's DistributedFileSystem class is
> only assuming Hadoop's FileSystem class.
> By generalizing the Flink DFS class, we can easily support other file systems
> implementing the Hadoop FS class, such as the GoogleHadoopFileSystem, Tachyon
> and others.
