[jira] [Created] (HDFS-6414) xattr modification operations are
based on state of latest snapshot instead of current version of inode.
Chris Nauroth created HDFS-6414:
-----------------------------------
Summary: xattr modification operations are based on state of latest snapshot instead of current version of inode.
Key: HDFS-6414
URL: https://issues.apache.org/jira/browse/HDFS-6414
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: HDFS XAttrs (HDFS-2006)
Reporter: Chris Nauroth
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.
