Subject [jira] Updated: (HADOOP-836) unit tests fail on windows (/C:/cygwin/... is invalid)
Date Wed, 20 Dec 2006 00:30:22 GMT
     [ http://issues.apache.org/jira/browse/HADOOP-836?page=all ]

Owen O'Malley updated HADOOP-836:
---------------------------------

    Attachment: dos-dfs.patch

Paths without schemes were being used in MapTask.java. So the local split file was being written
into dfs by mistake. This patch fixes that problem, makes the dfs client reject illegal names
immediately, and adds a new static method to get the local file system.
