Michael Moser commented on NIFI-3579:
-------------------------------------
I confirmed that if the ./content_repository directory does not exist, then
Files.getFileStore(path) throws NoSuchFileException.
path.toFile().getTotalSpace() succeeds, however, but returns 0. I have a
feeling that FileSystemRepository won't work very well if it thinks it's
capacity it 0.
Since ./content_repository is created in the FileSystemRepository constructor
(just 50 lines higher), maybe we should verify that the OS thinks the directory
exists before moving on?

> Key: NIFI-3579
> URL: https://issues.apache.org/jira/browse/NIFI-3579
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.2.0, 1.1.1
> Environment: Win 10 with Oracle JDK 1.8.0_121 on NTFS
> Reporter: Puspendu Banerjee
> Assignee: Puspendu Banerjee
> Priority: Critical
> Labels: windows
> Attachments: nifi-app.log
>
>
> 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}
