> In REEF-1827 [1], the URI used to specify remote and local files were changed to use the "AbsolutePath". [2]
> This means that a file specified as "hdfs://my/file" becomes "/my/file" and the hdfs:// is assumed by the `dfs` command.
> This is fine if you are using vanilla HDFS, but for cases like Blob Storage in Azure, there is a special prefix, `wasb://` that is used instead of `hdfs://`. This means that the AbsolutePath method trims off the wasb, and this Copy() function instead attempts to download the file from the local HDFS instead of WASB.
> We need to revisit this issue and keep the full path for copies while also keeping proper casing in the path.
