-------------------------------------------

             Summary: Listing encryption zones still fails when deleted EZ is not a direct
child of snapshottable directory
                 Key: HDFS-12336
                 URL: https://issues.apache.org/jira/browse/HDFS-12336
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
    Affects Versions: 3.0.0-alpha4
            Reporter: Wellington Chevreuil
            Assignee: Wellington Chevreuil
            Priority: Minor


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.
