Akira AJISAKA commented on HDFS-5059:
-------------------------------------
Hi [~boky01], I agree that this is a duplicate of HDFS-5111. Thank you for
closing this issue, but the resolution should be "Duplicate" instead of
"Fixed". "Fixed" is used when the source code is actually changed in this
issue. I'll reopen this to change the resolution.
> Unnecessary permission denied error when creating/deleting snapshots with a
> non-existent directory
> --------------------------------------------------------------------------------------------------
>
> Key: HDFS-5059
> URL: https://issues.apache.org/jira/browse/HDFS-5059
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: snapshots
> Affects Versions: 3.0.0-alpha1
> Reporter: Stephen Chu
> Assignee: Andras Bokor
> Priority: Trivial
> Labels: newbie
>
> As a non-superuser, when you create and delete a snapshot but accidentally
> specify a non-existent directory to snapshot, you will see an
> extra/unnecessary permission denied error right after the "No such file or
> directory" error.
> {code}
> [schu@hdfs-snapshots-vanilla ~]$ hdfs dfs -deleteSnapshot /user/schuf/ snap1
> deleteSnapshot: `/user/schuf/': No such file or directory
> deleteSnapshot: Permission denied
> [schu@hdfs-snapshots-vanilla ~]$ hdfs dfs -createSnapshot /user/schuf/ snap1
> createSnapshot: `/user/schuf/': No such file or directory
> createSnapshot: Permission denied
> {code}
> As the HDFS superuser, instead of the "Permission denied" error you'll get an
> extra "Directory does not exist" error.
> {code}
> [root@hdfs-snapshots-vanilla ~]# hdfs dfs -deleteSnapshot /user/schuf/ snap1
> deleteSnapshot: `/user/schuf/': No such file or directory
> deleteSnapshot: Directory does not exist: /user/schuf
> {code}
