Andrew Wang reopened HDFS-5035:
-------------------------------
Re-opening to backport to branch-2.2.
> getFileLinkStatus and rename do not correctly check permissions of symlinks
> ---------------------------------------------------------------------------
>
> Key: HDFS-5035
> URL: https://issues.apache.org/jira/browse/HDFS-5035
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 3.0.0, 2.1.0-beta
> Reporter: Andrew Wang
> Assignee: Andrew Wang
> Fix For: 2.3.0
>
> Attachments: hdfs-5035-1.patch, hdfs-5035-2.patch
>
>
> Operations like getFileLinkStatus and rename operate on symlinks, not symlink
> targets. However, permission checks right now are being done on the symlink
> target, resulting in wonky behavior.
> This is similar to HDFS-4765, which fixed the same problem for delete.
