> Scenario:
>    1. Open the file for append()
>    2. Trigger append pipeline setup by adding some data.
>    3. Consider RECEIVING IBRs of DNs reaches NN first.
>    4. updatePipeline() rpc sent to namenode to update the pipeline.
>    5. Now, if complete() is called on the file even before closing the pipeline, then block will be COMPLETE, even before block is actually FINALIZED at DN side and file will be closed.
