7. After you committed your change into your local repo, you should be able to create a patch using the following command: 

   Code Block
   $ git format-patch -n HEAD~

   This command should create a git patch file under the current directory. Attach the patch file to the Apache JIRA and provide your comment about the solution. An Apache Ranger committer should be able to review your patch and provide feedback or commit to Apache Ranger.
