>                 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, hbase 1.1.1
>            Reporter: Nikolay
>            Priority: Critical

> 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*
