Thanks a lot [~xiaochen] for the help here. Attached a patch for branch-2.

> Key: HDFS-12336
> URL: https://issues.apache.org/jira/browse/HDFS-12336
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: encryption, hdfs
> Affects Versions: 3.0.0-alpha4
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Minor
> Fix For: 3.0.0-beta1

> The fix proposed on HDFS-11197 didn't cover the scenario where the EZ deleted
> but still under a snapshot is not a direct child of the snapshottable
> directory.
> Here the code snippet proposed on HDFS-11197 that would avoid the error
> reported by *hdfs crypto -listZones* when a deleted EZ is still under a given
> snapshot:
> {noformat}
> INode lastINode = null;
> if (inode.getParent() != null || inode.isRoot()) {
> INodesInPath iip = dir.getINodesInPath(pathName, DirOp.READ_LINK);
> lastINode = iip.getLastINode();
> }
> if (lastINode == null || lastINode.getId() != ezi.getINodeId()) {
> continue;
> }
> {noformat}
> It will ignore EZs when it's a direct child of a snapshot, because its parent
> inode will be null, and it isn't the root inode. However, if the EZ is not
> directly under snapshottable directory, its parent will not be null, and it
> will pass this check, so it will fail further due *absolute path required*
> validation error.
> I would like to work on a fix that would also cover this scenario.
