>                 Key: IMPALA-13870
>                 URL: https://issues.apache.org/jira/browse/IMPALA-13870
>             Project: IMPALA
>          Issue Type: Improvement
>          Components: Backend
>            Reporter: Yida Wu
>            Priority: Major
>
> StringVal may not have a null terminator in its pointer, so its length must 
> be considered when using it. Relying only on the pointer can lead to 
> incorrect usage. Implementing the << operator for StringVal could help reduce 
> such errors.
> However, this may require incresing the minimum C++ standard for udf.h to 
> C++11 in Impala 5.
