Steve Loughran commented on HADOOP-13449:
-----------------------------------------
regarding create() on a path. S3A isn't strict enough (HADOOP-13321) . It
checks the dest path is there and not a directory, but doesn't go up the tree.
It should. we know it should, but we also know how much slower things would be.
I'm hoping to make this something done asynchronously between creating the file
and actually committing the write in the final close(). That is, fail later,
rather than sooner —but do fail before anything is materialized (HADOOP-13654).
