Steve Loughran commented on HADOOP-16776:
-----------------------------------------

bq. I'm appalled and dismayed. You're blocking fixes for a critical data 
corruption bug due to a personal interest in advancing branch-3? We've been 
telling customers for months that it was impossible for distcp to copy the 
wrong data and they must be overwriting the s3 destination.

sorry, I'd missed this.

Sorry, I'd thought we had backported the -direct option everywhere, which is 
why I didn't think it was so important.

If we don't have -direct in a release, yes, we should eliminate this. So I'm 
going to re-open and we can get it into branch-2, even if not the 2.8 release,
