> Running a count star on yelp biz dataset
> {code:sql}
> SELECT count(*) FROM dfs.`/path/to/yelp-business.json`
> {code}
> yields *1,584* rows. However, running count on a specific field like so
> {code:sql}
> SELECT count(business_id) FROM dfs.`/path/to/yelp-business.json`
> {code}
> 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.
