Hi All, 2.0 is a good opportunity to enhance our ZK information. See DRILL-4543: Advertise Drill-bit ports, status, capabilities in ZooKeeper. This change will simplify YARN integration.
This enhancement will change the “public API” in ZK. To Parth’s point, we can do so in a way that old clients work - as long as a Drill-bit uses default ports. I’ve marked this JIRA as a candidate for 2.0.
