[jira] [Created] (BOOKKEEPER-834) test case error in test class TestDiskChecker

zhaijia created BOOKKEEPER-834:
----------------------------------

             Summary: test case error in test class TestDiskChecker
                 Key: BOOKKEEPER-834
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-834
             Project: Bookkeeper
          Issue Type: Bug
          Components: bookkeeper-server
         Environment: Linux /tmp dir size > 2GB
            Reporter: zhaijia
            Assignee: zhaijia
             Fix For: 4.3.1


In test class TestDiskChecker, test case will fail if tmp dir's usableSpace / totalSpace > 0.95, because threshold will be a negative number.
 
     public void testCheckDiskFull() throws IOException {
        File file = File.createTempFile("DiskCheck", "test");
        long usableSpace = file.getUsableSpace();
        long totalSpace = file.getTotalSpace();
        float threshold =
                (1f - ((float) usableSpace / (float) totalSpace)) - 0.05f;        
 < === if "usableSpace / totalSpace" is 0.99, then threshold is -0.04, this is invalid.
        diskChecker.setDiskSpaceThreshold(threshold, threshold);
        diskChecker.checkDiskFull(file);
    }
