stack commented on HADOOP-5744:
-------------------------------
Thanks Hairong. Any comment on the unqualified 'delay' made mention of in the
spec? What kind of time scale should we be thinking in? If it is an 'hour' as
I believe is the current default for lease timeout, hbase-like applications
will have given up the wait long before. If its in the tens of seconds -- ~30
seconds -- as I'm currently seeing in HBASE-4379 patches I'm helping Dhruba
test, then that is still too long but tolerable in a first release, as long as
it can be improved on over time ("Instantaneous" would be the ideal). Thanks.

> 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.
