> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: HDFS XAttrs (HDFS-2006)
> Reporter: Chris Nauroth
> Assignee: Andrew Wang
> Fix For: HDFS XAttrs (HDFS-2006)
>
> Attachments: hdfs-6414.1.patch, hdfs-6414.2.patch

>
> {{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.
