> We have an integration test suite that starts up an embedded version of zookeeper as
part of a suite of services.
> However because it doesn't register a shutdown handler, we get lots of warnings that
look like this
> 17-05-30 15:04:56 achambers.local ERROR [org.apache.zookeeper.server.ZooKeeperServer:472]
- ZKShutdownHandler is not registered, so ZooKeeper server won't take any action on ERROR
or SHUTDOWN server state changes
> My java is a bit rusty but I think I can't create one of these shutdown handlers from
outside the "org.apache.zookeeper.server" package because the constructor has not been marked
"public". Would it be possible to do so?
