Work Description: steveloughran commented on pull request #3463:
URL: https://github.com/apache/hadoop/pull/3463#issuecomment-922977734
1. Is the current behaviour actually causing a problem?
1. Have you looked at all the implementations of fs.getXAttrs() and verified
that they always throw UnsupportedOperationException if unsupported.
I can see from a purism perspective this is the correct thing to do. But I
worry that changing it now will break things.
After all, if an IOE is raised here for some reason (network, auth etc)
distcp will go on to fail shortly afterwards
