Bikas Saha commented on HADOOP-8973: ------------------------------------ Thanks for following up on my comments. Looks good. Minor comment. I think we added a check for java version and have used it to enable java api's for java 7, if available. If java 7 File.canWrite etc are going to work on Windows (like mentioned in some comments above) then we could enable the API path when (!Windows or Java>6). Please do open a jira to fix this issue in branch-1-win too. > DiskChecker cannot reliably detect an inaccessible disk on Windows with NTFS > ACLs > --------------------------------------------------------------------------------- > > Key: HADOOP-8973 > URL: https://issues.apache.org/jira/browse/HADOOP-8973 > Project: Hadoop Common > Issue Type: Bug > Components: util > Affects Versions: 3.0.0 > Reporter: Chris Nauroth > Assignee: Chris Nauroth > Attachments: HADOOP-8973.3.patch, > HADOOP-8973-branch-trunk-win.2.patch, HADOOP-8973-branch-trunk-win.patch > > > DiskChecker.checkDir uses File.canRead, File.canWrite, and File.canExecute to > check if a directory is inaccessible.
