> Key: ZOOKEEPER-1652
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1652
> Project: ZooKeeper
> Issue Type: Bug
> Components: java client
> Affects Versions: 3.4.5
> Reporter: Sean Bridges
> Assignee: Sean Bridges
> Priority: Critical
> Attachments: ZOOKEEPER-1652.patch
>
>
> When connecting to zookeeper, the client does a reverse dns lookup on the
> hostname. In our environment, the reverse dns lookup takes 5 seconds to
> fail, causing zookeeper clients to connect slowly.
> The reverse dns lookup occurs in ClientCnx in the calls to adr.getHostName()
> {code}
> setName(getName().replaceAll("\\(.*\\)",
> "(" + addr.getHostName() + ":" + addr.getPort() + ")"));
> try {
> zooKeeperSaslClient = new
> ZooKeeperSaslClient("zookeeper/"+addr.getHostName());
> } catch (LoginException e) {
> {code}
