Our system will refuse to process this dataset because of lack of suggest target.
(Pdb) self.all_dataset.metadata.query(('0', ALL_ELEMENTS))['dimension']['length'] 1 (Pdb) self.all_dataset Dataset(id='uu1_dh_dataset_TRAIN', name='NULL', location_uris='('file:///Users/muxin/Desktop/ISI/dsbox-env/data/datasets/seed_datasets_current/uu1_datasmash/TRAIN/dataset_TRAIN/datasetDoc.json',)')
It is probably the dataset (which has 3 columns actually) gives only 1 for dimension in metadata.

This is probably related to issue #228 . For some reason they have moved away from the convention that resource id '0' is always the target resource.

I just pushed a partial fix. Muxin would you please try running it on the dataset again.
