> Key: DRILL-4560
> URL: https://issues.apache.org/jira/browse/DRILL-4560
> Project: Apache Drill
> Issue Type: Sub-task
> Components: Server
> Affects Versions: 1.6.0
> Reporter: Paul Rogers
> Assignee: Sorabh Hamirwasia
> Priority: Minor
> Fix For: 1.9.0
>
>
> ZKClusterCoordinator notifies listeners of type DrillbitStatusListener when
> drillbits disappear from ZooKeeper. The YARN Application Master (AM) also
> needs to know when bits register themselves with ZK. So, ZKClusterCoordinator
> should change to detect new Drill-bits, then call
> DrillbitStatusListener.drillbitRegistered with the new Drill-bits.
