     [ https://issues.apache.org/jira/browse/DRILL-3845?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Deneche A. Hakim updated DRILL-3845:
------------------------------------
    Summary: UnorderedReceiver shouldn't terminate until it receives a final batch  (was: 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).
