> When handling {{ADD JAR}}, PR #8909 constructs a {{java.io.File}} first using the input jar path, and then converts it into a URL ([here|https://github.com/apache/spark/pull/8909/files#diff-d613c921507243c65591c003a348f5f3R180]). This works file for local file path without a URL scheme (e.g. {{/tmp/a.jar}}). However, {{java.io.File.toURI}} returns unexpected result when given a path containing a URL scheme (e.g. {{file:///tmp/a.jar}} or {{hdfs://host:9000/path/to/a.jar}}):
> {noformat}
> scala> new java.io.File("file:///tmp/file").toURI
> res1: java.net.URI = file:/Users/lian/local/src/spark/workspace-a/file:/tmp/file
> {noformat}
> The consequence is that, although the {{ADD JAR}} command doesn't fail immediately, the jar is actually not added properly.
