> Project: IMPALA
> Issue Type: Sub-task
> Components: Distributed Exec
> Affects Versions: Impala 3.3.0

> Proper cancellation wasn't ever implemented for this code path, so if the
> wait time is set high, threads can get blocked indefinitely even if the
> coordinator cancelled the query.
> I don't think it's hard to do the right thing - signal the filter and wake
> up the thread when the finstance is cancelled.
