> Currently, on Windows the hadoop wrapper script (hadoop-config.cmd) assumes its the only
place that uses JAVA_LIBRARY_PATH and initializes it to a blank line.
> set JAVA_LIBRARY_PATH=
> This prevents anyone from setting this outside of the hadoop wrapper (say hadoop-config.cmd)
for their own native libraries.
> The fix is pretty simple. Don't initialize it to '' and append the native libs like normal.

> This is the same fix that was done for *nix as part of HADOOP-6453.
