             Summary: Add operator << support for StringVal
                 Key: IMPALA-13870
                 URL: https://issues.apache.org/jira/browse/IMPALA-13870
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Yida Wu


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 would require incresing the minimum C++ standard for udf.h to 
C++11 in Impala 5.
