----------------------------------
Assignee: Kezhu Wang (was: Jordan Zimmerman)
> EnsembleTracker "configToConnectionString" method doesn't include zookeeper
> chroot
> -----------------------------------------------------------------------------------
>
> Key: CURATOR-593
> URL: https://issues.apache.org/jira/browse/CURATOR-593
> Project: Apache Curator
> Issue Type: Bug
> Reporter: Yang
> Assignee: Kezhu Wang
> Priority: Major
> Fix For: 5.6.0
>
>
> The bug was found on curator 4.2 version and it's still in the master branch.
> It can be reproduced by running a zookeeper quorum
> If you have a zookeeper connection string *localhost:2181/foobar* and using
> curator library.
> [EnsembleTracker.configToConnectionString|https://github.com/apache/curator/blob/master/curator-framework/src/main/java/org/apache/curator/framework/imps/EnsembleTracker.java#L168]
> will try to re-build the zookeeper connection string by using all the hosts
> in the quorum into the connection string(*127.0.0.1:2181,127.0.0.1:2182/*),
> but doesn't include zookeeper zk_chroot when reconstructing connection
> string.
> It's normally fine because it's not in-used, but when there is a session
> timeout trigger zookeeper watcher
> [expire|https://github.com/apache/curator/blob/master/curator-client/src/main/java/org/apache/curator/ConnectionState.java#L255]
> ConnectionState class will try to reset the connection by using
> [HandleHolder.getZooKeepe|https://github.com/Honglun/curator/blob/master/curator-client/src/main/java/org/apache/curator/HandleHolder.java#L87]r
> , the new connection string generated by above
> [EnsembleTracker.configToConnectionString|https://github.com/apache/curator/blob/master/curator-framework/src/main/java/org/apache/curator/framework/imps/EnsembleTracker.java#L168]
> method will be in-use during the reconnect.
> so it will try to connect to *127.0.0.1:2181,127.0.0.1:2182 (without /foobar
> zh_chroot)*
