> HADOOP-17597 set policy of reacting to hsync() on an s3 output stream to be 
> one of :Fail, warn, with default == fail.
> I propose downgrading this to warn. We've done it internally, after having it 
> on fail long enough to identify which processes were doing either of
> * having unrealistic expectations about the output stream (fix: move off s3)
> * were using hflush() as a variant of flush(), with the failure being an 
> over-reaction
