      Description

      HttpFs seems to have these problems:

      1. can't set permissions to 777 at file creation or 1777 with setpermission
      2. does not accept 01777 permissions (which is valid in WebHdfs)

      WebHdfs
      curl -X PUT "http://localhost:50070/webhdfs/v1/tmp/test-perm-webhdfs?permission=1777&op=MKDIRS&user.name=hue&doas=hue"

      {"boolean":true}

      curl "http://localhost:50070/webhdfs/v1/tmp/test-perm-webhdfs?op=GETFILESTATUS&user.name=hue&doas=hue"
