In the constructor above, it is likely not a huge deal since it's the constructor and if any Exception gets thrown, NiFi will fail to startup. However, here it is a much bigger concern, as this is called from a few different places where IOException is caught. > 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: 1.2.0, 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 > Fix For: 1.2.0 > > 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} -- This message was sent by Atlassian JIRA (v6.3.15#6346)
