Brice Dutheil commented on ZOOKEEPER-1356: ------------------------------------------ It seems so. I'm looking forward the release of 3.4.8 by the way ;P Which would greatly simply the deployment on docker container. > Avoid permanent caching of server IPs in the client > ---------------------------------------------------- > > Key: ZOOKEEPER-1356 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1356 > Project: ZooKeeper > Issue Type: Bug > Components: java client > Affects Versions: 3.3.4, 3.4.2 > Reporter: Neha Narkhede > Assignee: Neha Narkhede > > Relevant conversation on the dev mailing list - > https://email.corp.linkedin.com/owa/redir.aspx?C=87f3d1e78c96438c8115e450f410d010&URL=http%3a%2f%2fmarkmail.org%2fmessage%2f3vzynx6rgurubf3p%3fq%3dPerforming%2bno%2bdowntime%2bhardware%2bchanges%2bto%2ba%2blive%2bzookeeper%2bcluster%2blist%3aorg%252Eapache%252Ehadoop%252Ezookeeper-dev > Basically, the client caches the list of server IPs internally and maintains > that list for the entire lifetime of the client. This limits the ability to > remove/change a server node from a zookeeper cluster, without having to > restart every client. Also, two levels of IP caching, one in the JVM and one > in the zookeeper client code seems unnecessar. > It would be ideal to provide a config option that would turn off this IP > caching in the client and re-resolve the host names during the reconnect. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
