impala::AggregationNode::Close
[ https://issues.apache.org/jira/browse/IMPALA-7397?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Thomas Tauber-Marshall resolved IMPALA-7397.
--------------------------------------------
Resolution: Fixed
Fix Version/s: Impala 3.1.0
> dcheck in impala::AggregationNode::Close
> ----------------------------------------
>
> Key: IMPALA-7397
> URL: https://issues.apache.org/jira/browse/IMPALA-7397
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 3.1.0
> Reporter: Michael Brown
> Assignee: Thomas Tauber-Marshall
> Priority: Blocker
> Labels: crash, query_generator
> Fix For: Impala 3.1.0
>
>
> The dcheck is {{Check failed: expr_results_pool() == nullptr || expr_results_pool()->total_allocated_bytes() == 0}}. The random query generator found this numerous times. I was able to reproduce it, and the dcheck fails on all 3 impalads. Stack is the same on all 3.
