> allow/disallowSnapshot on EZ roots shouldn't fail due to trash
> provisioning/emptiness check

> Key: HDFS-15689
> URL: https://issues.apache.org/jira/browse/HDFS-15689
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs
> Affects Versions: 3.4.0
> Reporter: Siyao Meng
> Assignee: Siyao Meng
> Priority: Major
> Labels: pull-request-available
> Time Spent: 1h 20m

> h2. Background
> 1. HDFS-15607 added a feature that when
> {{dfs.namenode.snapshot.trashroot.enabled=true}}, allowSnapshot will
> automatically create a .Trash directory immediately after allowSnapshot
> operation so files deleted will be moved into the trash root inside the
> snapshottable directory.
> 2. HDFS-15539 prevents admins from disallowing snapshot if the trash root
> inside is not empty
> h2. Problem
> 1. When {{dfs.namenode.snapshot.trashroot.enabled=true}}, currently if the
> directory (to be allowed snapshot on) is an EZ root, it throws
> {{FileAlreadyExistsException}} because the trash root already exists
> (encryption zone has already created an internal trash root).
> 2. Similarly, at the moment if we disallow snapshot on an EZ root, it may
> complain that the trash root is not empty (or delete it if empty, which is
> not desired since EZ will still need it).
> h2. Solution
> 1. Let allowSnapshot succeed by not throwing {{FileAlreadyExistsException}},
> but informs the admin that the trash already exists.
> 2. Ignore {{checkTrashRootAndRemoveIfEmpty()}} check if path is EZ root.
