I'd like to move forward with https://issues.apache.org/jira/browse/AURORA-1669 asap; ie: removing legacy (Twitter) commons zookeeper libraries used for Aurora leader election in favor of Apache Curator libraries. The change submitted in https://reviews.apache.org/r/46286/ is now live in Aurora 0.14.0 and Apache Curator based service discovery can be enabled with the Aurora scheduler flag `-zk_use_curator`. I'd like feedback from users who enable this option. If you have a test cluster where you can enable `-zk_use_curator` and exercise leader failure and failover, I'd be grateful. If you have moved to using this option in production with demonstrable improvements or even maintenance of status quo, I'd also be grateful for this news. If you've found regressions or new bugs, I'd love to know about those as well.
Thanks in advance to all those who find time to test this out on real systems!
