Steven Phillips commented on DRILL-3845:
----------------------------------------
Based on your comment, it seems like the upstream fragment that runs for an
hour is supposed to be terminated. Is that correct? If so, that seems to be the
real problem. Why is it not terminating?
> Partition sender shouldn't send the "last batch" to a receiver that sent a
> "receiver finished" to the sender

> Even if a receiver has finished and informed the corresponding partition
> sender, the sender will still try to send a "last batch" to the receiver when
> it's done. In most cases this is fine as those batches will be silently
> dropped by the receiving DataServer, but if a receiver has finished +10
> minutes ago, DataServer will throw an exception as it couldn't find the
> corresponding FragmentManager (WorkEventBus has a 10 minutes recentlyFinished
> cache).
> DRILL-2274 is a reproduction for this case (after the corresponding fix is
> applied).
