Rationale for this change
Very minor. This source file cannot be compiled on its own manually, due to missing stringstream headers. This fixes that. Otherwise we get
implicit instantiation of undefined template
errors.Context is we build Apache Arrow in a separate build system, Buck. As such, we do not (and cannot) 100% mirror the CMake build. In the past we've also had to patch header issues like: 529e08c. Thus, this change is for posterity to avoid having to custom patches on every new release.
