Examples of QuorumUtil

org.apache.zookeeper.test.QuorumUtil
Utility for quorum testing. Setups 2n+1 peers and allows to start/stop all peers, particular peer, n peers etc.

Examples of org.apache.zookeeper.test.QuorumUtil


        // set the snap count to something low so that we force log rollover
        // and verify that is working as part of the epoch rollover.
        SyncRequestProcessor.setSnapCount(7);


        qu = new QuorumUtil(1);
        startAll();


        for (int i = 0; i < zkClients.length; i++) {
            zkClientWatchers[i] = new CountdownWatcher();
            int followerPort = qu.getPeer(i+1).peer.getClientPort();
