I'm wondering why HDFS security support should be mandatory? Append makes sense because there's no way to have a durable system without it. Security is currently an optional feature & implemented as an HBase co-processor (vs core), correct? Is there a problem (other than minor inconvenience) with using introspection APIs for security in the core and then warning if security is enabled but the API is unreachable?
