---------------------------------
> 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}
