Description

Reviewing the code, s3a has the problem raised in HADOOP-6688: deletion of a child entry during a recursive directory delete is propagated as an exception, rather than ignored as a detail which idempotent operations should just ignore.

the exception should be caught and, if a file not found problem, logged rather than propagated
