[jira] Updated: (ZOOKEEPER-829) Add /zookeeper/sessions/* to allow inspection/manipulation of client sessions
[ https://issues.apache.org/jira/browse/ZOOKEEPER-829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Michael Xu updated ZOOKEEPER-829: - Attachment: zookeeper-829.diff hi everyone, here is a patch for this issue. the server creates zknodes at /zookeeper/sessions with the sessionID as the name (NOT hex-encoded, uses base-10 representation of the sessionID ). Any client writing anything to a session node causes the session to be expired. I will write unit tests when I get a chance, but I'd like feedback on design-wise what may need to be changed in order to include it officially. Likely, the next step will be making a test mode specifically for zookeeperserver so clients can use this functionality of managing sessions themselves. michael > Add /zookeeper/sessions/* to allow inspection/manipulation of client sessions > - > > Key: ZOOKEEPER-829 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-829 > Project: Zookeeper > Issue Type: New Feature > Components: server >Reporter: Todd Lipcon > Attachments: zookeeper-829.diff > > > For some use cases in HBase (HBASE-1316 in particular) we'd like the ability > to forcible expire someone else's ZK session.
