Hi [~zhz], we should definitely fix it since we don't want an incompatible change in 2.8.0.
{{DistributedFileSystem#getTrashRoot}} does throw so we should just fix it. We can remove
the IncompatibleChange label after the fix. I will review your fix patch. Thanks for reporting
this.

It looks like {{TrashPolicyDefault#getCurrentTrashDir}} never throws IOException so we can
simply remove the {{throws IOException}} annotation. Thanks for reporting this.

> Currently, "Soft Delete" is only supported if the whole encryption zone is deleted. If
you delete files whinin the zone with trash feature enabled, you will get error similar to
the following 
> {code}
> rm: Failed to move to trash: hdfs://HW11217.local:9000/z1_1/startnn.sh: /z1_1/startnn.sh
can't be moved from an encryption zone.
> {code}
> This JIRA is proposed to support trash for deletion of files within encryption zone.
