[GitHub] [helix] i3wangyi opened a new issue #687: ZkClient re-installs the
watcher for a non-existence path for the node is deleted
i3wangyi opened a new issue #687: ZkClient re-installs the watcher for a non-existence path for the node is deleted
URL: https://github.com/apache/helix/issues/687
*Root cause*
--
pathStatRecord.recordPathStat(getStat(path, true), notificationTime);
--
The getStat(path, true) method not only returns the Stat of the path but also adds the exists watcher (exists watcher can be added even the path is non-existed). The path parameter in the context of node deleted action is the path of deleted node, which means it adds the watcher to a non-existence zookeeper path.
