Hi, In the new MapReduce API's in Hadoop 0.20.2 version, the methods setup( ) and cleanup( ) are run ONCE at the beginning and at the end of a task. How is this functionality provided in the older MapReduce API's in the 0.20.2 version of Hadoop.Can functionality similar to setup( ) be implemented in configure( )?
Also, what is the use of the OutputCommitter.java class, could someone please provide an example of its usage for better understanding. Thanks in advance, Sahana
