Example 1 with CreateRaftGroupOp

use of com.hazelcast.cp.internal.raftop.metadata.CreateRaftGroupOp in project hazelcast by hazelcast.

the class RaftInvocationManager method invokeCreateRaftGroup.

private void invokeCreateRaftGroup(String groupName, int groupSize, long groupIndex, List<RaftEndpoint> members, InternalCompletableFuture<RaftGroupId> resultFuture) {
    InternalCompletableFuture<CPGroupSummary> f = invoke(raftService.getMetadataGroupId(), new CreateRaftGroupOp(groupName, members, groupIndex));
    f.whenCompleteAsync((group, t) -> {
        if (t == null) {
            resultFuture.complete((RaftGroupId) group.id());
            triggerRaftNodeCreation(group);
        } else {
            if (t instanceof CannotCreateRaftGroupException) {
                logger.fine("Could not create CP group: " + groupName + " with members: " + members + " and group index: " + groupIndex, t.getCause());
                invokeGetMembersToCreateRaftGroup(groupName, groupSize, resultFuture);

            }
            resultFuture.completeExceptionally(t);
