[jira] [Commented] (CURATOR-299) Copious "Failed to find watcher"
log messages when closing Curator 3.0 recipes
[ https://issues.apache.org/jira/browse/CURATOR-299?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15132324#comment-15132324 ]
Jordan Zimmerman commented on CURATOR-299:
------------------------------------------
The logs is actually coming from the ZK client and should be removed there. However, Curator should probably not try to remove non-existent watchers.
