----------------------------------

             Summary: [C++] NullArray::IsNull always returns false and 
NullArray::IsValid always returns true
                 Key: ARROW-13319
                 URL: https://issues.apache.org/jira/browse/ARROW-13319
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
    Affects Versions: 3.0.0, 5.0.0
            Reporter: Nate Clark


NullArray::SetData sets null_bitmap_data_ to NULLPTR which IsNull and IsValid 
interpret as all values are not null. However, null_count() and length() will 
return the same value which makes it seem like IsNull() and IsValid() should 
return true and false respectively.
