Hi, 1 - Hadoop uses several ports to run. It exists ports for HDFS, for the MapReduce JvmTasks, etc. I don't know how I can identify all the ports that a MapReduce and HDFS uses. I'm running the wordcount example, and I would like to see what ports are open and what are their purpose. Where can I get this information?
2 - Running the example of the WordCount in MapReduce, I noticed that it's created several new process. I know that it's created new process for a TaskTracker, for a JobTracker and for a TaskInProgress. Is this all the processes that are created on MapReduce during the execution of the wordcount example? How many processes are created in total? Thanks, -- Pedro
