Examples of org.lilyproject.util.zookeeper.StateWatchingZooKeeper

org.lilyproject.util.zookeeper.StateWatchingZooKeeper
This implementation of {@link ZooKeeperItf} is meant for use as a global ZooKeeper handlewithin a ZK-dependent application.
It will:
- on startup (= constructor) wait for the ZK connection to come up, if it does not come up within the session timeout an exception will be thrown. This avoids the remainder of the application starting up in the absence of a valid ZK connection.
- when the session expires or the ZK connection is lost for longer than the session timeout, it will shut down the application.
So this is a good solution for applications which can not function in absence of ZooKeeper.

        HBASE_PROXY = new HBaseProxy();
        HBASE_PROXY.start();


        IdGenerator idGenerator = new IdGeneratorImpl();
        configuration = HBASE_PROXY.getConf();
        zooKeeper = new StateWatchingZooKeeper(HBASE_PROXY.getZkConnectString(), 10000);
        hbaseTableFactory = new HBaseTableFactoryImpl(HBASE_PROXY.getConf());


        RepositoryModel repositoryModel = new RepositoryModelImpl(zooKeeper);


        typeManager = new HBaseTypeManager(idGenerator, configuration, zooKeeper, hbaseTableFactory);
