> [C++] Hdfs and java dlls fail to load when built for Windows with MSVC

> If I build the cpp library with MSVC for windows and try to use the hdfs io
> interface, the dynamic library loads fail.
> The reason is that in file hdfs-internal.cc on two occasions the __WIN32
> define is checked instead of _WIN32. The former is not set by MSVC. I checked
> that these are the only two locations in the arrow library where the flag
> __WIN32 is used, so all we need to do is replace these two references in
> hdfs-internal.cc.
