> Let's consider the following scenario:
> * Start one node and upload data.
> * Start a new node (note that this step triggers rebalancing).
> * Start explicit transaction and try to update atomic cache (it is assumed
> that atomic operation are allowed for use inside transactions, see Ignite
> system property DFLT_ALLOW_ATOMIC_OPS_IN_TX)
> {code:java}
> IgniteTransactions txs = ignite.transactions();
> try (Transaction tx = txs.txStart()) {
> atomicCache.put();
> tx.commit();
> }
> {code}
> Let's assume that the transaction mapped on the topology version that is
> related to {{NODE_JOIN}} event,
> on the other hand, the corresponding request
> {{GridNearAtomicAbstractUpdateRequest}} can be validated on the primary node
> using the next topology version, triggered by {{CacheAffinityMessage}}.
> {code:java|title=GridDhtAtomicCache.java}
> private void updateAllAsyncInternal0() {
> ...
> if (validateCache) {
> GridDhtTopologyFuture topFut = top.topologyVersionFuture();
> // There is a chance that the topFut is not done yet!
> assert topFut.isDone() : topFut;
> Throwable err = topFut.validateCache(ctx, req.recovery(), false,
> null, null);
> ...
> }
> }{code}
> That is the root cause of the {{AssertionError}} mentioned above.
