>             Project: Apache Drill
>          Issue Type: Bug
>            Reporter: Vlad Rozov
>            Assignee: Vlad Rozov
>            Priority: Critical
>             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.
