Summary: When configuring the IP address of the zk server on the
client side to connect to zk, the connection establishment time is high
Key: ZOOKEEPER-4811
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4811
Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.7.1, 3.7.0
Reporter: yangoofy
When configuring the IP address of the zk server on the client side to connect
to zk, the connection establishment time is high。Mainly because Obtaining the
hostname of the address takes approximately 5 seconds. 3.4.6 has mechanism to
safely avoid reverse DNS lookup，but 3.7 don't do that。
1.What's the reasone？
2.Can we modify the method StaticHostProvider/resolve() to avoid reverse DNS
lookup?
