Colin Patrick McCabe commented on HDFS-4685:
--------------------------------------------
Thanks for tackling this Chris. it looks good overall.
Now that we have HDFS-5286 (flatten inode directory) in, doesn't it make sense
to have the ACLs associated with an {{INode}} be stored as {{Features}}, rather
than using a separate data structure? I didn't see any mention in the design
doc-- maybe I missed it.
