Thanks for the clarification Bernd, I guess I don't understand how there can be two copyright
holders for the same pieces of
software without an explicit copyright grant at the time of the donation.

Anyway, I realized that In this case we'd just have a local fork (or a clone rather) of asynchhbase
with local changes inside of
Salesforce and copyrightis not concern as long as there is a suitable license that lets us
do this.
(I guess "fork" has a distinct different meaning)

That's the most tricky part in Open Source.
At first, you have to differentiate Copyright and Licensing.
Apache projects are Apache-licensed, so you can take the code and do
with it what you want (except claiming copyright). (This is the very
short version.)
For all contributions to Apache projects (including code and
documentation) the original contributor holds copyrights. There is no
transfer of copyright over to Apache.
However, the ASF holds copyright for the combined work that is the
released product.
A missing copyright notice is no indication that there is no copyright.

All you need to care for as a user/consumer of Apache software is the
license. Enjoy.

The PMC is responsible to make sure that releases indeed allow for and
fully are Apache Licensed.

For more details, pls ask on the legal mailing list or see the link
given in HBASE-3870.
