Sergey Shelukhin resolved HIVE-13928.
-------------------------------------
Resolution: Not A Problem
By design. Quotes may be forcing a different type; overall floating type
equalily is not expected to work.
> Hive2: float value need to be single quoted inside where clause to return
> rows when it doesn't have to be

> Key: HIVE-13928
> URL: https://issues.apache.org/jira/browse/HIVE-13928
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.1.0
> Reporter: Takahiko Saito
> Priority: Critical
>
> The below select where with float value does not return any row:
> {noformat}
> 0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> drop table test;
> No rows affected (0.212 seconds)
> 0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> create table test (f float);
> No rows affected (1.131 seconds)
> 0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> insert into table test values
> (-35664.76),(29497.34);
> No rows affected (2.482 seconds)
> 0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> select * from test;
> +------------+--+
> | test.f |
> +------------+--+
> | -35664.76 |
> | 29497.34 |
> +------------+--+
> 2 rows selected (0.142 seconds)
> 0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> select * from test where f =
> -35664.76;
> +---------+--+
> | test.f |
> +---------+--+
> +---------+--+
> {noformat}
> The workaround is to single quote float value:
> {noformat}
> 0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> select * from test where f =
> '-35664.76';
> +------------+--+
> | test.f |
> +------------+--+
> | -35664.76 |
> +------------+--+
> 1 row selected (0.163 seconds)
> {noformat}
