Jing Zhao commented on HDFS-6643:
---------------------------------

The patch looks pretty good to me. But it looks like the fields of 
LongBitFormat do not need to be public (they are only used inside of 
LongBitFormat)?

> Refactor INodeFile.HeaderFormat and 
> INodeWithAdditionalFields.PermissionStatusFormat

> The use of them are very similar.  We should change INodeFile.HeaderFormat to 
> enum and refactor them for code reuse.
