Nikolay updated DRILL-4221:
---------------------------
Description:
Drill returns incorrect result when rows more than *832*.
When I run query
bq. SELECT count(row_key) FROM hbase.`ns:events`
query returns *833*(correct result).
If I run query
bq. SELECT count(\*) FROM hbase.`ns:events`
query returns *832*(incorrect result).
Also incorrect results can be for other type of queries. For example if I run
query
bq. SELECT count(`ns:events`.CF.column1) FROM hbase.`ns:events`
query returns *833*(correct results) but if I run query with"WHERE CLAUSE":
bq. SELECT count(`ns:events`.CF.column1) FROM hbase.`ns:events` where row_key
BETWEEN 'a' AND 'f'
In this case the query returns incorrect result(*832*, range from '*a*' to
'*f*' is enough for getting all rows, all keys starts with 'b')
Also strange behavior is continued, when I added another 1000 rows, then the
query that returns an incorrect number of rows (*832*), began to return the
result *831*
