-----------------------------------
Summary: Count star returns invalid result
Key: DRILL-1764
URL: https://issues.apache.org/jira/browse/DRILL-1764
Project: Apache Drill
Issue Type: Bug
Reporter: Hanifi Gunes
@fc58c69 [current head]
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.
