Description

It looks like, the data structure processor is not properly initialized when a client node connects to a cluster that changes its own state (state transition from the inactive state to active).

reproducer attached.

UPDATE
It seems to me, the root cause of the issue is that joinFut is always completed with false.

GridClusterStateProcessor.java

    /** {@inheritDoc} */
    @Override public void onStateFinishMessage(ChangeGlobalStateFinishMessage msg) {
        DiscoveryDataClusterState discoClusterState = globalState;

        if (msg.requestId().equals(discoClusterState.transitionRequestId())) {
            ...
            TransitionOnJoinWaitFuture joinFut = this.joinFut;

            if (joinFut != null)
                joinFut.onDone(false);
            ...
        }
        else
            U.warn(log, "Received state finish message with unexpected ID: " + msg);
    }

On the other hand, this value is used to determine the state of the cluster when a new node joins the cluster

IgniteKernal.java

    public void start(
            DiscoveryLocalJoinData joinData = ctx.discovery().localJoin();

            IgniteInternalFuture<Boolean> transitionWaitFut = joinData.transitionWaitFuture();

            ...
            boolean active;

            if (transitionWaitFut != null) {
                if (log.isInfoEnabled()) {
                    log.info("Join cluster while cluster state transition is in progress, waiting when transition finish.");
                }

                active = transitionWaitFut.get();
            }
            else
                active = joinData.active();

            startTimer.finishGlobalStage("Await transition");
            ...
    }
