Subject [GitHub] zookeeper issue #689: ZOOKEEPER-3183:Notifying the WatcherCleaner thread and...

Github user tumativ commented on the issue:

    I realized that processing remaining watchers is not a good idea without knowing the context
of the shutdown. The shutdown contract itself is stop processing. I have modified the JIRA
    It targets below improvements.
    - Notify the  WatcherCleaner thread during shutdown if it is waiting for dead watchers
get the certain number(watcherCleanThreshold) 
    - Notify the threads who are waiting on totalDeadWatchers, this can happen when pending
watchers are reached maximum
    -Stop taking incoming dead watcher and adding to deadWatchers even cleaner thread is stopped.
