Example 1 with ManagedTransaction

use of com.hortonworks.registries.storage.transaction.ManagedTransaction in project streamline by hortonworks.

the class StreamsModule method setupPlaceholderTopologyVersionInfo.

private void setupPlaceholderTopologyVersionInfo(StreamCatalogService catalogService) {
    if (transactionManager == null)
        throw new RuntimeException("TransactionManager is not initialized");
    // it's one time setup hence just use it as local variable
    ManagedTransaction mt = new ManagedTransaction(transactionManager, TransactionIsolation.DEFAULT);
    try {

            TopologyVersion versionInfo = catalogService.getTopologyVersionInfo(StreamCatalogService.PLACEHOLDER_ID);
