Help Regarding MAPREDUCE

Hi,

should i look at if i want to know how hadoop mapreduce communication takes
place. Is it only IPC or there are some other directories also that i should
work with???

Take a look at org.apache.hadoop.mapred.TaskTracker.MapOutputServlet which
is inside src/mapred/org/apache/hadoop/mapred/TaskTracker.java
