Running a count star on yelp biz dataset

SELECT count(*) FROM dfs.`/path/to/yelp-business.json`

yields 1,584 rows. However, running count on a specific field like so

SELECT count(business_id) FROM dfs.`/path/to/yelp-business.json`

returns 15,585 rows as expected since the file has exact the same row count.

Running count star must return the exact number of records in the file.
