Harsh, Sorry for creating confusion. The question is if i have a single node setup and i give Sysout statements in maptask.java and reducetask.java. {HADOOP_HOME}$ant build {HADOOP_HOME}$start all daemons {HADOOP_HOME}$ run wordcount example
Yes i am able to see o/p in *.out files of tasktrackers. Q>Does the map/reduce task run time displayed in web GUI is decent/accurate enough ? Q>If i want to do find the IO rate of a task, will the task run time divided by total number of FIle bytes and HDFS bytes read/written give it approximately ? Q>Does the FILE Bytes read for the reduce task include the map output record bytes read non-locally over network or the bytes read locally from the map output records after they are copied locally ? Thanks, Arun
