Chaoyu Tang resolved HIVE-12678.
--------------------------------
Resolution: Information Provided
[~nbrenwald] I am resolving this JIRA since it has been fixed in Hive 2.1.0 and
1.3.0 in HIVE-13039.
> BETWEEN relational operator sometimes returns incorrect results against
> PARQUET tables
> --------------------------------------------------------------------------------------
>
> Key: HIVE-12678
> URL: https://issues.apache.org/jira/browse/HIVE-12678
> Project: Hive
> Issue Type: Bug
> Affects Versions: 1.1.0, 1.2.1
> Reporter: Nicholas Brenwald
> Assignee: Chaoyu Tang
>
> When querying a parquet table, the BETWEEN relational operator returns
> incorrect results when hive.optimize.index.filter and
> hive.optimize.ppd.storage are enabled
> Create a parquet table:
> {code}
> create table t(c string) stored as parquet;
> {code}
> Insert some strings representing dates
> {code}
> insert into t select '2015-12-09' from default.dual limit 1;
> insert into t select '2015-12-10' from default.dual limit 1;
> insert into t select '2015-12-11' from default.dual limit 1;
> {code}
> h3. Example 1
> This query correctly returns 3:
> {code}
> set hive.optimize.index.filter=true;
> set hive.optimize.ppd.storage=true;
> select count(*) from t where c >= '2015-12-09' and c <= '2015-12-11';
> +------+--+

> | 3 |
> +------+--+
> {code}
> This query incorrectly returns 1:
> {code}
> set hive.optimize.index.filter=true;
> set hive.optimize.ppd.storage=true;
> select count(*) from t where c between '2015-12-09' and '2015-12-11';
> +------+--+
> | _c0 |
> +------+--+
> | 1 |
> +------+--+
> {code}
> Disabling hive.optimize.findex.filter resolves the problem. This query now
> correctly returns 3:
> {code}
> set hive.optimize.index.filter=false;
> set hive.optimize.ppd.storage=true;
