The problem go away with the patch. Better to dive deep to figure out why it happens. This
affects MultiQuery_11.

> Similar to the comments in POSimpleTezLoad:
> {code}
>     /**
>      * Previously, we reused the same Result object for all results, but we found
>      * certain operators (e.g. POStream) save references to the Result object and
>      * expect it to be constant.

> {code}
> Tuples put into binaryInputQueue get changed when it is actually processed. Not exactly
sure why, but make a copy of the tuple solves the issue.
