> 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: Bug
> Components: sql
> Affects Versions: 2.7.6
> Reporter: Andrey Mashenkov
> Assignee: Andrey Mashenkov
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
