> So, the big question here is what should go in the audit log? All failures,
> or just "permission denied" failures? Or, to put it a different way, if
> someone attempts to do something and it fails because a file doesn't exist,
> is that worth an audit log entry?
> We are currently inconsistent on this point. For example, concat,
> getContentSummary, addCacheDirective, and setErasureEncodingPolicy create an
> audit log entry for all failures, but setOwner, delete, and setAclEntries
> attempt to only create an entry for AccessControlException-based failures.
> There are a few operations, like allowSnapshot, disallowSnapshot, and
> startRollingUpgrade that never create audit log failure entries at all. They
> simply log nothing for any failure, and log success for a successful
> operation.
> So to summarize, different HDFS operations currently fall into 3 categories:
> 1. audit-log all failures
> 2. audit-log only AccessControlException failures
> 3. never audit-log failures
> Which category is right? And how can we fix the inconsistency
