> Executing a merge region before the flush table is completed will result in an NPE error for the flush table and cause it to fail
> Triggering logic
>  # Execute the flush table command.
>  # Merge regions before the flush is completed.
>  # After the merge is completed, the two parent regions will be cleaned up.
>  # An NPE will be reported when the flush operation is performed on that parent region.
