[jira] [Created] (ZOOKEEPER-4250) Support resolving zookeeper quorum from DNS

Aihua Xu created ZOOKEEPER-4250:
-----------------------------------

             Summary: Support resolving zookeeper quorum from DNS
                 Key: ZOOKEEPER-4250
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4250
             Project: ZooKeeper
          Issue Type: Improvement
          Components: server
    Affects Versions: 3.4.13
            Reporter: Aihua Xu


This is to improve resolving zookeeper quorum from configured DNS entry. Currently zookeeper supports quorum from individual host. 

Instead of configuring a list of zk servers, we can provide a DNS entry for such list and then  resolve them into zk servers. With that, any physical server changes just require DNS refresh without no downtime.
