-----------------------------------------

             Summary: SQL: Query reduce can fail with NPE on retry.
                 Key: IGNITE-12444
                 URL: https://issues.apache.org/jira/browse/IGNITE-12444
             Project: Ignite
          Issue Type: Test
          Components: sql
            Reporter: Andrey Mashenkov


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.
