Review comment:
> Also the "file:" scheme doesn't generally like "//".
Not sure what you mean here (agree that manual URI creation is not the most
appropriate way but considering the mentioned URI resolution this seemed the
most reasonable way).
```
scala> val cpTempDir = new Path("file://" + tempDir + "/temporary1")
cpTempDir: org.apache.hadoop.fs.Path =
file:/var/folders/t_/w90m85fn2gjb1v0c24wrfrxm0000gp/T/temporary1
