### Description of PR
Fix Hadoop RunJar for Windows. The Windows filesystem does not recognize the
POSIX permissions, and it was causing the directory creation failure. If the
filesystem does not support POSIX permissions, switch to using the user-based,
ACL-based permissions that work on Windows.
### How was this patch tested?
I added a test to TestRunJar and ran it first to reproduce the bug on
Windows. After I changed RunJar.java, I ran TestRunJar on Windows and confirmed
it runs successfully.

- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
