I'm trying to write unit tests using miniDFSCluster and it's throwing the error below

java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$Windows.access0(Ljava/lang/String;I)Z

any pointers to resolve this issue?

With errors like this, I use three steps

  1. Find out what it is looking for 

         In this case, *org.apache.hadoop.io.nativeio.NativeIO$Windows.access0*

  2. Find out what jar/lib it is in.

         I don't use the Windows version, but I believe it is in hadoop.dll - 
     you'll have to check this.

  3. Find out where I'm telling it to use that jar/lib

I was able to resolve this error by following these steps:

  1. Download hadoop.dll and winutils.exe in the same version that I'm using in the sbt/maven configuration, you can find these files in all versions of hadoop here: link

  2. Put these 2 files in your %hadoop directory%\bin folder

  3. make sure that %hadoop directory%\bin is listed under PATH in your device's environmental path(if using windows)

then the code should work just fine.
