             Summary: Result data gets mixed up when various tables have a column "label"
                 Key: DRILL-4436
                 URL: https://issues.apache.org/jira/browse/DRILL-4436
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.5.0
         Environment: Drill 1.5.0 with Zookeeper on CentOS 7.0 
            Reporter: Vincent Uribe


We have two tables in a MySQL database:
CREATE TABLE `Gender` (
  `genderId` bigint(20) NOT NULL AUTO_INCREMENT,
  `label` varchar(15) NOT NULL,
  PRIMARY KEY (`genderId`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;

CREATE TABLE `Civility` (
  `civilityId` bigint(20) NOT NULL AUTO_INCREMENT,
  `abbreviation` varchar(15) NOT NULL,
  `label` varchar(60) DEFAULT NULL
  PRIMARY KEY (`civilityId`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=latin1;

With a query on these two tables with Gender.label as 'gender' and Civility.label as 'civility', we obtain, depending of the query :
* gender in civility
* civility in the gender
* NULL in the other column (gender or civility)

if we drop the table Gender and recreate it with like this:
CREATE TABLE `Gender` (
  `genderId` bigint(20) NOT NULL AUTO_INCREMENT,
  `label2` varchar(15) NOT NULL,
  PRIMARY KEY (`genderId`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;

Everything is fine.

I guess something is wrong with the metadata...
