------------------------------
Summary: Not correct number of rows when rows are fetched from
hbase storage
Key: DRILL-4221
URL: https://issues.apache.org/jira/browse/DRILL-4221
Project: Apache Drill
Issue Type: Bug
Components: Storage - HBase
Affects Versions: 1.3.0
Environment: Linux 14.04, JAVA 1.7.0_67
Reporter: Nikolay
Priority: Critical
Drill returns incorrect result when rows more than 832. When I run query SELECT
count(row_key) FROM hbase.`ns:events`, query returns 833(correct result), If I
run query 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 SELECT count(`ns:events`.CF.column1) FROM hbase.`ns:events`,
query returns 833(correct results) but if I run query with"WHERE CLAUSE": "
SELECT count(`ns:events`.CF.column1) FROM hbase.`ns:events` where row_key
BETWEEN 'a' AND 'f' " (Range from 'a' to 'f' is enough for getting all rows,
all keys starts with 'b') in this case the query returns incorrect result(832).
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
