Review Comment:
   Perhaps this is out of scope for this PR since for other delete operations 
we only stop retry on FileNotFoundException, but it seems there are other cases 
where we should stop retrying like permission denied errors. 
https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java#L2848
 or AccessControlExceptions in HDFS cases.
