Hi, I am working on TCP communications in Hadoop and I would like to know if it is existing a way to separate easily communications between the processes of HDFS and MapReduce (without modifying source code).
For example, when I run "wordcount" example, there is HDFS communications and MapReduce communications and I am not able to distinguish which packet belong to HDFS or to MapReduce. A way could be to use odd port number for HDFS and even port number for MapReduce, but I think I have to modify source code. Thanks, Regards, -- Rémi Druilhe
