Data race stems from here:
{noformat}
Group grp = modes.near ? cluster.forCacheNodes(name(), true, true,
false) : cluster.forDataNodes(name());
Collection<ClusterNode> nodes = grp.nodes();
if (nodes.isEmpty())
return new GridFinishedFuture<>(0);
ctx.kernalContext().task().setThreadContext(TC_SUBGRID, nodes);
return ctx.kernalContext().task().execute(
new SizeTask(ctx.name(), ctx.affinity().affinityTopologyVersion(),
peekModes), null);
{noformat}
Method grp.nodes() returns PredicateCollectionView, which size depends on
Ignite state. It can pass nodes.isEmpty() check and become empty later.
