FYI: Note that there is no need for copyright in hbase src code going forward
Henry Yandell a while back noted that the copyright is not actually
needed in Apache source files. See
https://issues.apache.org/jira/browse/HBASE-3870 for a reference to
the mail he sent me pointing to Apache doc where the header format is
described.

My guess: Because it's not the same pieces. Think of a painting
exibited in a museum surrounded by other pieces of art in a special
artistic arrangement.
The painter would hold copyright for his painting, as do the other
artists for their pieces, but the arranging artist holds copyright for
the whole assemblement.
He can do this as the other artists (or the owner of the pieces who
may not even hold copyright) have granted him permission ('licensed')
to incorporate the pieces.
That's kind of how I imaging it works.

I don't know anything about asynchhbase. Is it part of Apache HBase?
Is it Apache-release code? As long as there is no official PMC-vetted
Apache release for the code, you cannot be sure it is properly
licensed.
You'd better consult your company's policy with respect to open source usage.

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.

Ah OK, so that's how we could fork asynchhbase without writing over the copyright?
