   > Do we need to add provisionTrash command for WebHdfs as well?
   
   Good point. I think so, yes.
   
   Update: As I was attempting to add `PROVISIONSNAPSHOTTRASH` to WebHDFS, I realized `NamenodeWebHdfsMethods` is already server code. But the whole provision trash logic are on the **client** side (same as provision EZ trash). This would also imply that WebHDFS `ALLOWSNAPSHOT` won't trigger provision snapshot trash at the moment.
   
   Note WebHDFS doesn't support encryption zone commands (create, list, etc.).
   
   I have opened another jira [HDFS-15612](https://issues.apache.org/jira/browse/HDFS-15612) for discussion on WebHDFS support for provision snapshot trash. Let's rule WebHDFS out in this jira for now. @bshashikant
