Subject [jira] Updated: (HADOOP-3074) URLStreamHandler for the DFS
Date Tue, 25 Mar 2008 15:29:24 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3074?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Christophe Taton updated HADOOP-3074:
-------------------------------------

    Attachment: 3074-20080325a.patch

I dug concerning file:// URLs and the previous patch does not work for these URLs.
This happens because of the late loading of Configuration resource files (which itself relies
on URLs).
The new patch forces the load of such resource files before setting the new handler factory,
thus allowing it to handle file:// URLs too.

The code has also been cleaned (FSDataInput/OutputStream replaced with Input/OutputStream).

> This issue aims at providing a handler to resolve DFS URLs ("hdfs://host:port/file/to/path"),
so that such URLs can be read using the URL API (mainly {{InputStream url.openStream()}}).
> This allows the use of a {{URLClassLoader}} which would serve classes directly from the
DFS.
