> On HBASE-25279 there was some discussion and difference of opinion about
> having ZK watcher pool threads be daemonized. This is not necessarily a
> problem but should be reconsidered.
> Daemon threads are subject to abrupt termination during JVM shutdown and
> therefore may be interrupted before state changes are complete or resources
> are released.
> As long as ZK watchers are properly closed by shutdown logic the pool threads
> will be terminated in a controlled manner and the JVM will exit.
