Subject Problem with BackupNode?
Date Wed, 15 Jun 2011 22:42:54 GMT
Hi,

My repo is one week old  and the change I did was to modify the
Configuration object at BackupNode.initialize() to make the name and edit
dirs to other directories, so I could run both namenode and backup node in
the same machine.  When I copied a file to HDFS, the follow exception was
below was thrown. Have anyone seem that ?
