If we create this from the absolute path, it appears that the string ends
up with `C:/../..` form and⨠`Utils.resolveURI` recognises `C` as the scheme,
causing "No FileSystem for scheme: C"⨠exception.
It looks `Path` can handle this but we can't currently replace
`Utils.resolveURI` to⨠`Path` due to of some corner case of behaviour changes.
For example, with `Path`, "hdfs:///root/spark.jar#app.jar" becomesâ¨
"hdfs:///root/spark.jar%23app.jar" but with `Utils.resolveURI`,â¨
"hdfs:///root/spark.jar#app.jar" becomes "hdfs:///root/spark.jar#app.jar".
`Utils.resolveURI` is being called via,
