Andrew Wang commented on HDFS-9799:
-----------------------------------
Throwing a new checked exception is definitely incompatible, good find.
How about the getTrashRoots method that was added which also throws
IOException? Seems like we should do a similar change for parity.
> Reimplement getCurrentTrashDir to remove incompatibility
