Nico Kruber created FLINK-8737:
----------------------------------
Summary: Creating a union of UnionGate instances will fail with
UnsupportedOperationException when retrieving buffers
Key: FLINK-8737
URL: https://issues.apache.org/jira/browse/FLINK-8737
Project: Flink
Issue Type: Sub-task
Components: Network
Reporter: Nico Kruber
Fix For: 1.5.0
FLINK-8589 introduced a new polling method but did not implement
{{UnionInputGate#pollNextBufferOrEvent()}}. This prevents UnionGate instances
from containing a UnionGate instance which is explicitly allowed by its
documentation and interface.
