---------------------------------

             Summary: Casting to BigInt from Varchar produces wrong results
                 Key: DRILL-366
                 URL: https://issues.apache.org/jira/browse/DRILL-366
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Mehant Baid
            Priority: Blocker


Can be reproduced using the following plan:

{
    head:{
        type:"APACHE_DRILL_PHYSICAL",
        version:"1",
        generator:{
            type:"manual"
        }
    },
        graph:[
        {
            @id:1,
            pop:"json-scan",
            entries: [
                {
                    path : "/tmp/scan4.json"
                }
            ],
            storageengine: {
                "type": "json",
                "dfsName": "file:///"
            }
        },
        {
            pop:"project",
            @id:2,
            child: 1,
            exprs: [ {
              ref: "int",
              expr: "cast(integer as bigint)"     
            } ]
        },
        {
            @id: 3,
            child: 2,
            pop: "screen"
        }   
    ]         
} 

Input file, "/tmp/scan4.json":
{
  "integer" : "2008"
}
{
  "integer" : "2007"
}
{
  "integer" : "2006"
}

Output:
2008
2008
2008

>From the above output we notice that it always generates values corresponding to the first row. Looks like the buffer is not getting reset to the next row.
