> Project: HBase
> Issue Type: Bug
> Components: Zookeeper
> Affects Versions: 2.0.0, 1.1.0, 1.2.0
> Reporter: Stephen Yuan Jiang

>
> MiniZooKeeperCluster#startup() starts servers one-by-one, if everything is
> good, it would declare success of start:
> {code}
> public int startup(File baseDir, int numZooKeeperServers)
> ...
> // running all the ZK servers
> for (int i = 0; i < numZooKeeperServers; i++) {
> ...===> could throw exception in the loop and end the startup
> // Start up this ZK server
> standaloneServerFactory.startup(server);
> ...
> standaloneServerFactoryList.add(standaloneServerFactory);
> zooKeeperServers.add(server);
> }
> ...
> started = true;
> ...
> }
> {code}
> However, if exception throws in the middle of start up (eg. some servers
> already started), the MiniZooKeeperCluster#shutdown() would not shut down
> them and clean up resources.
> {code}
> public void shutdown() throws IOException {
> if (!started) {
> return;
> }
> ...
> }
> {code}
