Thanks Uma for ping me, and Rakesh for the work. Agree with Andrew and I think it makes sense
to throw FileNotFoundException for non-existent file.

> Presently calling {{dfs#getErasureCodingPolicy()}} on a non-existent file is returning
the ErasureCodingPolicy info. As per the [discussion|https://issues.apache.org/jira/browse/HDFS-8777?focusedCommentId=14981077&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14981077]
it has to validate and throw FileNotFoundException.
> Also, {{dfs#getEncryptionZoneForPath()}} API has the same behavior. Again we can discuss
to add the file existence validation in this case.
