Subject [jira] [Commented] (PHOENIX-4283) Group By statement truncating BIGINTs
Date Mon, 16 Oct 2017 05:22:01 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-4283?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16205443#comment-16205443
] 

James Taylor commented on PHOENIX-4283:
---------------------------------------

One last nit: swap the argument order here so that the expected value is first or the assertion
message if it were to fail would be confusing.

Then commit to 4.12-HBase-0.98, 4.x-HBase-0.98, and master branches.

>             Project: Phoenix
>          Issue Type: Bug
>    Affects Versions: 4.11.0
>            Reporter: Steven Sadowski
>            Assignee: Ethan Wang
>             Fix For: 4.12.1
>
>         Attachments: PHOENIX-4283-v2.patch, PHOENIX-4283.patch

> *Versions:*
> Phoenix 4.11.0
> HBase: 1.3.1
> (Amazon EMR: 5.8.0)
> *Steps to reproduce:*
> 1. From the `sqlline-thin.py` client setup the following table:
> {code:sql}
> CREATE TABLE test_table (
>     a BIGINT NOT NULL, 
>     c BIGINT NOT NULL
>     CONSTRAINT PK PRIMARY KEY (a, c)
> );
> UPSERT INTO test_table(a,c) VALUES(4444444444444444444, 5555555555555555555);
> SELECT a FROM (SELECT a, c FROM test_table GROUP BY a, c) GROUP BY a, c;
> {code}
> *Expected Result:*
> {code:sql}
> +----------------------+
> |          A           |
> +----------------------+
> | 4444444444444444444  |
> +----------------------+
> {code}
> *Actual Result:*
> {code:sql}
> +----------------------+
> |          A           |
> +----------------------+
> | 4444444444444000000  |
> +----------------------+
> {code}
> *Comments:*
> Having the two Group By statements together seems to truncate the last 6 or so digits
of the final result. Removing the outer (or either) group by will produce the correct result.
> Please fix the Group by statement to not truncate the outer result's value.
