Description

When FileContext.mkdir(..) is used to create a directory inside a parent directory (which has the setgid permission), the created directory loses the setgid permission.

We have noticed that in ContainerLocalizer.java:

  private static void initDirs(Configuration conf, String user, String appId,
      FileContext lfs, List<Path> localDirs) throws IOException {
       .
       .
      // $x/usercache/$user/appcache/$appId/output
      lfs.mkdir(new Path(appBase, OUTPUTDIR), null, false);
       .
       .
  }
