NSA Makes Contribution To Apache Hadoop Project
An anonymous reader writes "The National Security Agency has submitted a new database, Accumulo, to the Apache Foundation for incubation. Accumulo is based on the original BigTable paper with some extensions such as the ability to provide cell-level security. It appears there are some hurdles that must be cleared concerning copyright before the project could be accepted."
Possibly because they want someone else to maintain the code for them. This way the NSA gets to keep their cell-level security and sit back while others provide bug fixes and new features.
