Chris Nauroth commented on HDFS-5925:
-------------------------------------
Thank you for reviewing, Vinay. I implemented the check on fsimage initially
in HDFS-5899. Then, while working on HDFS-5914, Colin and Haohui raised their
concerns about these checks. We removed the fsimage check temporarily during
HDFS-5914, and now we're making the final decision to remove the fsimage and
edits checks permanently. That's why you don't see anything related to fsimage
in the current patch.
> ACL configuration flag must only reject ACL API calls, not ACLs present in
> fsimage or edits.

> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: HDFS ACLs (HDFS-4685)
> Reporter: Chris Nauroth
> Assignee: Chris Nauroth

> In follow-up discussion on HDFS-5899, we decided that it would cause less
> harm to administrators if setting {{dfs.namenode.acls.enabled}} to false only
> causes ACL API calls to be rejected. Existing ACLs found in fsimage or edits
> will be loaded and enforced.
