Description

If IgntieCompute.apply() is called on a client after reconnect, it fails. Reproducer code is attached. The problem is that RoundRobinLoadBalancingSpi (which is default one) is not notified about topology reset.

Sample stack trace:

class org.apache.ignite.IgniteException: Task topology does not have alive nodes: [TcpDiscoveryNode [id=50f56f53-bbf6-4d66-bfc5-02d801241e14, addrs=[127.0.0.1], sockAddrs=[/127.0.0.1:47500], discPort=47500, order=1, intOrder=1, lastExchangeTime=1476269284697, loc=false, ver=1.7.0#19700101-sha1:00000000, isClient=false]]
