HBase depends on agile-json, which includes the following phrase in its license:
"The Software shall be used for Good, not Evil."
Debian-Legal advised me, that for this phrase the software is considered non-free. As a consequence, hbase could not be included in the official Debian distribution but only in the contrib repository. I discussed this issue also with crockford, but he made it clear that he has no intention to change his license.
http://www.json.org lists several Java Json libraries. Maybe you could take another one with a more sane license text?
Yes, this issue is highly controversial and you'll most likely not spend the hours of work only because crockford and Debian are both bullheads.
Just keep this issue open as crockford-remembrance issue. May it help to fight the evil!
