   Mapreduce 7375 JobSubmissionFiles don't set right permission after mkdirs
   ### Description of PR
   JobSubmissionFiles provide getStagingDir to get Staging Directory.If stagingArea missing, method will create new directory with this.
   fs.mkdirs(stagingArea, new FsPermission(JOB_DIR_PERMISSION));
   It seems create new directory with JOB_DIR_PERMISSION,but this permission will be apply by umask.If umask too strict , this permission may be 000(if umask is 700).So we should change permission after create.
   
   ### How was this patch tested?
   
   
   ### For code changes:
   
   - [ ] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
   - [ ] 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 licensed in a way that is compatible for inclusion under [ASF 2.0](http://www.apache.org/legal/resolved.html#category-a)?
   - [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`, `NOTICE-binary` files?

Review Comment:
   Suggestion: different variable name for greater clarity, e.g. `dfsCluster`.
   
   Also, please use a `finally` block to guarantee calling `MiniDFSCluster#shutdown()` at the end of the test.

Review Comment:
   Does this test actually cover the bug? Should the test be configuring umask to 700 to simulate the bug more accurately?
   
   Ideally, this should be a test that 1) fails before applying the `JobSubmissionFiles` patch, and 2) starts passing after applying the `JobSubmissionFiles` patch.

   Nitpick: lower-case `conf` for local variables.

   @steveloughran , I don't think this one is a strong candidate for the next 3.3.5 RC.

   Please indent by 2 spaces instead of 4 to match Hadoop coding standards.
   
   Once that's done, I think this will be ready to commit. Thanks!
