Arpit Agarwal commented on HDFS-8831:
-------------------------------------
Hi [~zhz], we should definitely fix it since we don't want an incompatible
change in 2.8.0. It looks like {{TrashPolicyDefault#getCurrentTrashDir}} never
throws IOException so we can simply remove the {{throws IOException}}
annotation. Thanks for reporting this.
