Hi Andrew,

If you have specific questions, you might be better served by asking on
legal-discuss@apache.org

That said, I can try to give you the 10,000 foot view. Full disclaimer:
IANAL.

You can choose to apply the Apache Licence (AL) to your code without
submitting it to the Apache Software Foundation (ASF). However, if you are
submitting your code to the ASF, it must be ALv2 (v2 is the current
version). Kind of a square is a rectangle, but not all rectangles are
squares thing. An example of AL projects outside of the ASF includes
jcommander, hosted on GitHub, which Accumulo uses.

If you license your code as AL, then anybody else is free to take your
code, modify it, and either give away their changes, sell them, etc. Their
additions can be AL as well, or can be some other licence.

If you licence your code GPLv3, then anybody else is free to take your
code, modify it, and give away their changes as long as those changes are
also GPLv3. This is colloquially known as a viral licence.

ASF projects cannot use GPL code - a familiar example might be how Hadoop
(and Accumulo) does not ship with the LZO extensions, they must be
downloaded separately. ASF projects can use some other licenses such as MIT
and BSD as dependencies - apologies, I don't have the full list as I'm on
my phone right now. Search for ASF Compatible Licenses or something like
that.

Another caveat that you might want to consider, since I noticed that you
sent this mail from what looks like a work account, is what your companies'
policies are, if they are a stakeholder in the code. They might have no
input into this, or you might want to discuss the options with your
internal legal staff; I can't pretend to know your current arrangement.

tl;dr - Use AL if you want the simplest path to adoption in the Accumulo
code base, use GPL if you would like to make sure that nobody can make
proprietary changes and sell them.

Mike
