Hello All, I am doing some experiments with WordCount example running on hadoop cluster. I have some questions :
1) How can i monitor the output from mapper before flushing to reducer? ( Infact i want to see how the keys are sorted.) 2) In one of my experiments i need to disable the sort phase in Mapper and send unsorted data to reducer. Is there any way to disable this sort in mapper ? or i need to modify hadoop to disable it ? As i undestood in MapTask.java this functionality implemented. And ofcourse i dont want to set number of reducer to zero becouse i need to have atleast one reducer. So any idea how to disable the sort phase in mapper and monitor the output ? Best, Samaneh
