             Summary: Nifi Failed to Start: nio Files.getFileStore(Path) is buggy in Windows
                 Key: NIFI-3579
                 URL: https://issues.apache.org/jira/browse/NIFI-3579
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.1.1, 1.2.0
         Environment: Win 10 with Oracle JDK 1.8.0_121 on NTFS
            Reporter: Puspendu Banerjee
            Assignee: Puspendu Banerjee
            Priority: Critical


Nifi is failing to start due to IOException originating from FileSystemRepository during calls to {code:java}
Files.getFileStore(path).getTotalSpace();
Files.getFileStore(path).getUsableSpace();
 {code} with a read-access denied status.
It looks like a buggy JDK implementation as on the other hand the following code is yielding result:
{code:java}
path.toFile().getTotalSpace();
path.toFile().getUsableSpace();
{code}
Interestingly, the both of the codes are yielding same results for C:\ or System Drive.
*sample*
{code:java}
import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.Arrays;
import static java.lang.System.out;
public class Blah {
    public static void main(String [] args) throws IOException{
        String [] _paths= {"D:\\workspace\\nifi", "c:\\Program Files"};
        final float divisor=1024 * 1024 * 1024f;
        for(String _path : _paths) {
            try {
                Path path = Paths.get(_path);
                out.println(path.toFile().getTotalSpace() /divisor  + "GB");
                out.println(Files.getFileStore(path).getTotalSpace()/divisor +"GB");
            }catch (Exception ex){
                ex.printStackTrace();
            }
        }

    }
}
{code}
