Xiaoyu Yao commented on HDFS-9799:
----------------------------------

Thanks [~zhz] for the explanation. Agree with your changes on 
getTrashRoot()/getTrashRoots level. For the change in getTrashRoots, can we add 
some indication for partial results being returned at API level in addition to 
the log.

> Reimplement getCurrentTrashDir to remove incompatibility

> HDFS-8831 changed the signature of {{TrashPolicy#getCurrentTrashDir}} by 
> adding an IOException. This breaks other applications using this public API. 
> This JIRA aims to reimplement the logic to safely handle the IOException 
> within HDFS.
