Gabor Bota commented on HADOOP-13980:
-------------------------------------

[~mackrorysd], I've created the subtasks. I don't know what I wanted to do with 
handling {{Export metadatastore and S3 bucket hierarchy}} and {{export scan 
results in human readable format}} differently, it makes no sense to me now to 
separate those. 

> We can probably break this into more subtasks. If would be best if the 
> implementation had a sequence of specific "fixers" to address specific 
> discrepancies. "fixMissingParents", "fixOutOfDateEntries", etc.
I have handlers in the PR, the violation handler can log and fix the error. We 
can do complex stuff in a handler, but a handler cannot see other violations 
yet, just what it handles.
