> When a daemon node joins the cluster seems to switch to compatibility mode (allowing
nodes without baseline support). It prevents baseline nodes from being restarted.
> Example:
> {code}
> Ignite ignite1 = IgnitionEx.start("examples/config/persistentstore/example-persistent-store.xml",
"srv1");
> Ignite ignite2 = IgnitionEx.start("examples/config/persistentstore/example-persistent-store.xml",
"srv2");
> ignite2.cluster().active(true);
> IgnitionEx.setClientMode(true);
> IgnitionEx.setDaemon(true);
> Ignite daemon = IgnitionEx.start("examples/config/persistentstore/example-persistent-store.xml",
"daemon");
> IgnitionEx.setClientMode(false);
> IgnitionEx.setDaemon(false);
> ignite2.close();
> IgnitionEx.start("examples/config/persistentstore/example-persistent-store.xml", "srv2");
> {code}
> The attempt to restart ignite2 throws an exception:
> {code}
