[jira] Updated: (HADOOP-521) classloader problem for clients
[ http://issues.apache.org/jira/browse/HADOOP-521?page=all ]
Owen O'Malley updated HADOOP-521:
---------------------------------
Attachment: conf-classloader.patch
Use the classloader associated with the conf.
Sorry I missed the second call to getContextClassLoader in the method. I just reran my search and the only one left is the one in Configuration that is supposed to be there.
