> GridReduceQueryExecutor can fail with NPE on retry if it couldn't map during retry timeout.
> So, 'lastRun' can be null here
> {code:java}
>    if (attempt > 0 && retryTimeout > 0 && (U.currentTimeMillis() - startTime > retryTimeout)) {
>                 UUID retryNodeId = lastRun.retryNodeId();
>                 String retryCause = lastRun.retryCause();
>                 assert !F.isEmpty(retryCause);
> {code}
> Also assertion above is not correct. 
> It is possible, we failed to send request, then retried with success to remap.
> So, 'lastRun' would be not null, but cause is empty.
