>                 Key: SPARK-19971
>                 URL: https://issues.apache.org/jira/browse/SPARK-19971
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 2.1.0
>         Environment: macOS Sierra
>            Reporter: Tom Tang
>            Priority: Critical

> Let say we have a csv /tmp/1.csv :
> {code}
> cid,name
> -100224910923912596,jack
> -100224910923912595,tom
> -1,rose
> -2,marry
> -100,rose1
> -101,rose2
> {code}
> Use following SQL to define a view in Spark-SQL:
> {code}
> CREATE TEMPORARY VIEW T
> (
>   `cid` string,
>   `name` string
> )
> USING CSV
> OPTIONS (
>   path "/tmp/1.csv"
> );
> {code}
> Statement 1:
> {code}select * from T where cid = -100224910923912596; {code}
> Returns:
> {code}
> -100224910923912596	jack
> -100224910923912595	tom
> {code}
> Statement 2:
> {code}select * from T where cid = -100224910923912599;{code}
> it also returns:
> {code}
> -100224910923912596	jack
> -100224910923912595	tom
> {code}
> Unless you do, 
> {code}select * from T where cid = '-100224910923912596';{code}
> It returns: 
> {code}
> -100224910923912596	jack
> {code}
> However, i think the expected behaviour for statement 1 and 2 is pretty wired.
> Statement 4
> {quote}select * from T where cid = -100;{quote}
> Returns:
> {quote}-100	rose1{quote}
> And this just affect the large number, the smaller one seemed to be good.
> Does that look like a bug to you folks ?
> Thanks.
