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 ?
