      Description

      The Flink Runner's UnboundedSourceWrapper does not check whether the CheckpointMarkCoder is null. In this case, no checkpoint is required by the wrapped source.

        /**
         * Returns a {@link Coder} for encoding and decoding the checkpoints for this source, or
         * null if the checkpoints do not need to be durably committed.
         */
        @Nullable
        public abstract Coder<CheckpointMarkT> getCheckpointMarkCoder();
      

      We should skip checkpointing if no CheckpointMarkCoder is supplied.
