[jira] [Created] (ARROW-1003) Hdfs and java dlls fail to load when built for Windows with MSVC

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

             Summary: Hdfs and java dlls fail to load when built for Windows with MSVC
                 Key: ARROW-1003
                 URL: https://issues.apache.org/jira/browse/ARROW-1003
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
         Environment: Windows, MSVC
            Reporter: Balázs Gosztonyi


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.
