Subject [jira] Created: (HADOOP-1020) Path class on Windows seems broken
Date Wed, 14 Feb 2007 20:16:05 GMT
Path class on Windows seems broken
----------------------------------

                 Key: HADOOP-1020
                 URL: https://issues.apache.org/jira/browse/HADOOP-1020
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.11.1
            Reporter: Nigel Daley


Executing this code:

Path file = new Path("file:///", "C:/trunk/build/test/data");   or   Path file = new Path("C:/trunk/build/test/data");
FileSystem fs = file.getFileSystem(conf);
fs.mkdirs(file))

produces this exception.  It looks like it's defaulting to the DistributedFileSystem.
