Description

I've seen that all my logs comes with the message:

2011-01-25 10:41:57,479 INFO org.apache.hama.bsp.TaskRunner: attempt_201101251040_0002_m_000001_0 log4j:ERROR Could not find value for key log4j.appender.DEBUG
2011-01-25 10:41:57,479 INFO org.apache.hama.bsp.TaskRunner: attempt_201101251040_0002_m_000001_0 log4j:ERROR Could not instantiate appender named "DEBUG".

We need to fix rootLogger and, add task log appender.
