just put the following parameters into the VM arguments of your run
configuration:

-Dhadoop.home.dir=3D<your=5Fpath>\src\test\config\hadoop=5Fbin=5Fwindows
-Djava.library.path=3D<your=5Fpath>\src\test\config\hadoop=5Fbin=5Fwindows\=
bin

Matthias

Subject:	Executing DMLScript in Eclipse on Windows


Hi,

On OS X during development, I usually run SystemML using an Eclipse debug
configuration that uses DMLScript as the main class.

I tried doing the same thing on Windows, and when I do this, I see the
following winutils.exe exception:
16/05/27 12:01:54 ERROR util.Shell: Failed to locate the winutils binary in
the hadoop binary path
java.io.IOException: Could not locate executable null\bin\winutils.exe in
the Hadoop binaries.
    at org.apache.hadoop.util.Shell.getQualifiedBinPath(Shell.java:318)

If I build the project and run the standalone package (which has the
lib/hadoop/bin/ directory), I do not see this exception.

Does anyone have any advice about the best way to run DMLScript in Eclipse
on Windows without the exception? BTW, I usually use the
maven-eclipse-plugin to create my classpath.

Thanks,
Deron
