Andrew Wang updated HDFS-6414:
------------------------------
Attachment: hdfs-6414.1.patch
Thanks for the nice find Chris, patch attached which essentially follows your
suggestions.
I also found an additional issue surrounding quota handling when adding a
feature not present in the snapshot, simple fix and test for that as well.
> xattr modification operations are based on state of latest snapshot instead
> of current version of inode.

> {{XAttrStorage#updateINodeXAttrs}} modifies the inode's {{XAttrFeature}}
> based on reading its current state. However, the logic for reading current
> state is incorrect and may instead read the state of the latest snapshot. If
> xattrs have been changed after creation of that snapshot, then subsequent
> xattr operations may yield incorrect results.
