> Not sure how to reproduce it in the minicluster. I was playing around in Impala-2.12.0-rc1 on my cluster. It can be reproduced stably. My actions are:
> {code:java}
> [localhost:21000] default> compute incremental stats myTable;
> {code}
> Then in the webpage, the following subquery will be running:
> {code:java}
> SELECT COUNT(*), realdate FROM myTable GROUP BY realdate
> {code}
> Click its details, then click the "Fragment Instances" tab and the impalad crashed.
