> HADOOP-1700 and related issues have put a lot of efforts to provide the first
> implementation of append. However, append is such a complex feature. It turns
> out that there are issues that were initially seemed trivial but needs a
> careful design. This jira revisits append, aiming for a design and
> implementation supporting a semantics that are acceptable to its users.
