[jira] [Resolved] (IMPALA-8774) Crash in AggregatorNode::Open()
when computing statistics
[ https://issues.apache.org/jira/browse/IMPALA-8774?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tim Armstrong resolved IMPALA-8774.
-----------------------------------
Resolution: Cannot Reproduce
I narrowed down the crashed query to happening during computing stats on kudu tables during data load. I looped computing stats on functional_kudu and tpch_kudu for a long time and didn't reproduce it.

while ./tests/util/compute_table_stats.py --db_names=functional_kudu,tpch_kudu; do date; if [[ $(pgrep impalad | wc -l) -ne 3 ]]; then break; fi ; done
