Review comment:
@vanzin could you please clarify why it is wrong? Are you referring to this:
```
else {
args.jars = mergeFileLists(args.jars, resolvedMavenCoordinates)
if (args.isPython || isInternal(args.primaryResource)) {
args.pyFiles = mergeFileLists(args.pyFiles,
resolvedMavenCoordinates)
}
}
```
`Else` there covers all other cases like client mode at the launcher side
for other resource managers as well.
The logic in there is special for two cases for the K8s resource manager and
I need to use `resolvedMavenCoordinates`.
Do you mean move `else if` one line up?
