The current Argus solution already has integration with the core Hadoop components like HDFS,
Hive and HBase. There are work in progress to support additional Hadoop components, which
includes Knox. Anytime, we cross project boundaries, there were would be always challenges
wrt technical and political. Working this out within the community makes more sense, rather
than doing this outside. Not attempting would be counterproductive.

I don’t believe Argus existence is because HDFS or any other component is locked down or
dysfunctional. Each component will continue to evolve  (core features and security) overtime
based on their priority, severity and timeline. The option to externalize security is always
a good thing. Option to externalize is a well accepted notion in the community. Commercial
databases allow externalizing security, web applications externalize authentication and authorization,
there are vulnerability management systems for file system/software version, etc. I don’t
see a security provider like Argus or Sentry extending the native security as a risk or bad
thing, instead, a good motivation for projects (particularly new) to focus on their core features.


I also don’t feel this is a short term user demand. Security requirement changes on regular
basis and as different type of industries adopt hadoop, their security requirements might
be also different. They will look for different options for security and select what addresses
their needs.

Security is most effective when it is deployed as layered solution. Knox addresses the perimeter
security. Currently it is REST and they will extend it to support security for more external
API technologies. Argus will not replace it, but complement Knox by centralizing the administration
and common auditing. Sentry and Argus have some overlap, but at the core, they have different
philosophies and approach. Similar discussion can be made between no-sql projects like Apache
HBase, Apache Accumulo and Apache Cassandra. Varying options is always healthy.
