-----------------------------------------

             Summary: ChannelStateReader rejects requests about unkown channels (Unaligned checkpoints)
                 Key: FLINK-17323
                 URL: https://issues.apache.org/jira/browse/FLINK-17323
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Task
    Affects Versions: 1.11.0
            Reporter: Roman Khachatryan
            Assignee: Roman Khachatryan
             Fix For: 1.11.0


ChannelStateReader expects requests only for channels or subpartitions that have state.

In case of upscaling or starting from scratch this behavior is incorrect. It should return NO_MORE_DATA.
