> Listing encryption zones fails when deleting a EZ that is on a snapshotted 
> directory
> ------------------------------------------------------------------------------------

>                 Key: HDFS-11197
>                 URL: https://issues.apache.org/jira/browse/HDFS-11197
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: hdfs
>    Affects Versions: 2.6.0
>            Reporter: Wellington Chevreuil
>            Assignee: Wellington Chevreuil
>            Priority: Minor
>         Attachments: HDFS-11197-1.patch, HDFS-11197-2.patch

> If a EZ directory is under a snapshotable directory, and a snapshot has been 
> taking, then if this EZ is permanently deleted, it causes *hdfs crypto 
> listZones* command to fail without showing any of the still available zones.
> This happens only after the EZ is removed from Trash folder. For example, 
> considering */test-snap* folder is snapshotable and there is already an 
> snapshot for it:
> {noformat}
> $ hdfs crypto -listZones
> /user/systest           my-key
> /test-snap/EZ-1       my-key
> $ hdfs dfs -rmr /test-snap/EZ-1
> INFO fs.TrashPolicyDefault: Moved: 'hdfs://ns1/test-snap/EZ-1' to trash at: 
> hdfs://ns1/user/hdfs/.Trash/Current/test-snap/EZ-1
> $ hdfs crypto -listZones
> /user/systest           my-key
> /user/hdfs/.Trash/Current/test-snap/EZ-1  my-key 
> $ hdfs dfs -rmr /user/hdfs/.Trash/Current/test-snap/EZ-1
> Deleted /user/hdfs/.Trash/Current/test-snap/EZ-1
> $ hdfs crypto -listZones
> RemoteException: Absolute path required
> {noformat}
> Once this error happens, *hdfs crypto -listZones* only works again if we 
> remove the snapshot:
> {noformat}
> $ hdfs dfs -deleteSnapshot /test-snap snap1
> $ hdfs crypto -listZones
> /user/systest           my-key
> {noformat}
> If we instead delete the EZ using *skipTrash* option, *hdfs crypto 
> -listZones* does not break:
> {noformat}
> $ hdfs crypto -listZones
> /user/systest           my-key
> /test-snap/EZ-2  my-key
> $ hdfs dfs -rmr -skipTrash /test-snap/EZ-2
> Deleted /test-snap/EZ-2
> $ hdfs crypto -listZones
> /user/systest           my-key
> {noformat}
> The different behaviour seems to be because when removing the EZ trash 
> folder, it's related INode is left with no parent INode. This causes 
> *EncryptionZoneManager.listEncryptionZones* to throw the seen error, when 
> trying to resolve the inodes in the given path.
> Am proposing a patch that fixes this issue by simply performing an additional 
> check on *EncryptionZoneManager.listEncryptionZones* for the case an inode 
> has no parent, so that it would be skipped on the list without trying to 
> resolve it. Feedback on the proposal is appreciated.
