> 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}
> With HDFS-8830, we can support "Soft Delete" by adding the .Trash folder of the file being deleted appropriately to the same encryption zone.
