error using miniDFSCluster on windows

问题

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?

回答1:

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
