>             Project: Hadoop Hive
>          Issue Type: Bug
>          Components: Query Processor
>    Affects Versions: 0.5.0
>            Reporter: Abhinav Gupta
> I was running a query joining on bigint column with string column.
> And, result was incorrect because only "16 bytes seemed to be compared". The length of
value more than 16 bytes when represented as base-10. 
> The problem was fixed once I changed the join to (bigint = cast (string as bigint))
> Is the bug because of type conversion on join keys?
