BELUGA BEHR commented on HBASE-19678:
-------------------------------------
As mentioned in [HBASE-19679], this is actually still open. I just posted my
patch for a different issue under this ticket.
> HBase Admin security capabilities should be represented as a Set

> /**
> * Return the set of supported security capabilities.
> * @throws IOException
> * @throws UnsupportedOperationException
> */
> List<SecurityCapability> getSecurityCapabilities() throws IOException;
> {code}
> The comment says a "set" but it returns a List. A Set would be the most
> appropriate data structure here, an immutable one perhaps, because the code
> that interacts with it looks up information using the _contains_ method which
> would be served well by a Set. Please change this interface to return a Set.
