Examples with ClusterStateWatcher org.apache.asterix.event.service.ClusterStateWatcher used on opensource projects

Example 1 with ClusterStateWatcher

use of org.apache.asterix.event.service.ClusterStateWatcher in project asterixdb by apache.

the class StartConfig method execCommand.

@Override
protected void execCommand() throws Exception {
    InstallerDriver.initConfig(true);
    String asterixInstanceName = ((StartConfig) config).name;
    AsterixInstance instance = AsterixEventServiceUtil.validateAsterixInstanceExists(asterixInstanceName, State.INACTIVE);
    AsterixEventServiceUtil.createAsterixZip(instance);
    AsterixEventServiceClient client = AsterixEventService.getAsterixEventServiceClient(instance.getCluster());
    Patterns asterixBinaryTransferPattern = PatternCreator.INSTANCE.getAsterixBinaryTransferPattern(asterixInstanceName, instance.getCluster());
    client.submit(asterixBinaryTransferPattern);
    // Start the watcher
    ClusterStateWatcher stateWatcher = ServiceProvider.INSTANCE.getLookupService().startWatchingClusterState(asterixInstanceName);
    AsterixEventServiceUtil.createClusterProperties(instance.getCluster(), instance.getAsterixConfiguration());
    Patterns patterns = PatternCreator.INSTANCE.getStartAsterixPattern(asterixInstanceName, instance.getCluster(), false);
    client.submit(patterns);
    // Check the cluster state
    ClusterState clusterState = stateWatcher.waitForClusterStart();
    if (clusterState != ClusterState.ACTIVE) {
        throw new Exception("CC failed to start");
    }
    AsterixEventServiceUtil.deleteDirectory(InstallerDriver.getManagixHome() + File.separator + InstallerDriver.ASTERIX_DIR + File.separator + asterixInstanceName);
    AsterixRuntimeState runtimeState = VerificationUtil.getAsterixRuntimeState(instance);
    VerificationUtil.updateInstanceWithRuntimeDescription(instance, runtimeState, true);
