> During query cancellation, in case {{PartitionerDecorator.executeMethodLogic()}} is active (waiting on the {{latch}}), the wait will be interrupted and {{Futures}} 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 {{Vectors}} and {{DrillBufs}}. This eventually causes unallocated memory access and JVM crash as {{CustomRunnable}} may execute after income/outgoing batches are cleared.
