---------------------------------
Summary: {{PartitionerDecorator}} may close {{partitioners}} while
{{CustomRunnable}} are active during query cancellation
Key: DRILL-6295
URL: https://issues.apache.org/jira/browse/DRILL-6295
Project: Apache Drill
Issue Type: Bug
Reporter: Vlad Rozov
Assignee: Vlad Rozov
Fix For: 1.14.0
During query cancellation, in case
{{PartitionerDecorator.executeMethodLogic()}} is active (waiting on the
{{latch}}), the wait will be interrupted and {{Future}}s cancelled, but there
is no guarantee that all {{CustomRunnable}} terminate before returning from
{{PartitionerDecorator.executeMethodLogic()}}. On exit, both income and
outgoing batches are cleared, leading to clearing of underlying {{Vector}}s and
{{DrillBuf}}s. This eventually causes unallocated memory access and JVM crash
as {{CustomRunnable}} may execute after income/outgoing batches are cleared.
