Junping Du updated HDFS-9433:
-----------------------------
Release Note: Unify the behavior of dfs.getEZForPath() API when getting a
non-existent normal file and non-existent ezone file

> ------------------------------------------------------------------------------

>
> Presently {{dfs.getEZForPath()}} API is behaving differently for a
> non-existent normal file and non-existent ezone file:
> - If user pass a normal non-existent file then it will return null value. For
> example, {{Path("/nonexistentfile")}}
> - If user pass a non-existent file but which is under an existing encryption
> zone then it is returning the parent's encryption zone info. For example,
> {{Path("/ezone/nonexistentfile")}}
> Here the proposed idea is to unify the behavior by throwing
> FileNotFoundException. Please refer the discussion
