Example 1 with Transaction

use of com.hazelcast.transaction.impl.Transaction in project hazelcast by hazelcast.

the class ClusterStateManager method changeClusterState.

void changeClusterState(ClusterStateChange newState, Collection<Member> members, TransactionOptions options, int partitionStateVersion, boolean isTransient) {
    checkParameters(newState, options);
    if (isCurrentStateEqualToRequestedOne(newState)) {
        return;
    }
    NodeEngineImpl nodeEngine = node.getNodeEngine();
    TransactionManagerServiceImpl txManagerService = (TransactionManagerServiceImpl) nodeEngine.getTransactionManagerService();
    Transaction tx = txManagerService.newAllowedDuringPassiveStateTransaction(options);
    tx.begin();
    try {
        String txnId = tx.getTxnId();
        addTransactionRecords(newState, tx, members, partitionStateVersion, isTransient);
        lockClusterStateOnAllMembers(newState, nodeEngine, options.getTimeoutMillis(), txnId, members, partitionStateVersion);

    } catch (Throwable e) {
        if (e instanceof TargetNotMemberException || e.getCause() instanceof MemberLeftException) {
            // if new state is passive or frozen. They will be able to rejoin later.
