Hello Demian, Thanks for the answer. 1. I am using Java for writing the MapReduce Application. Can you tell me how to do it in JAVA? 2. In the mapper or reducer function, which command did you use to write the output? Is it going to write it in Log folder? I have multiple nodes and all of them may not be used running the job, How to find which logs are modified?
