Walter Su commented on HDFS-8444:
---------------------------------

Hi, [~tasanuma0829]! It's a different issue.
EC file doesn't have schema details. So ec files can't be deleted into Trash, 
which is a non-EC-dir, otherwise ec files lose schema details and can't be 
decoded.
EC zone dir has schema details. We move it, file still can be read.

> Erasure Coding: fix cannot rename a zone dir

> We want to rename it to {{/myZone}}.
> But it failed.
