I am running the wordcount example of hadoop on intel vtune for hotspot analysis. Command is bin/hadoop jar /usr/local/hadoop/hadoop-examples-1.2.1.jar wordcount inputfile outputfile. Hotspot analysis provides the modules information libzip.so, [compiled java code], [Dynamic code], libjvm.so, libc-2.17.so, libz.so.1.2.8 and [unknown]. My understanding is that [unknown] module is the wordcount application. However, to be sure I want to see what function inside the wordcount example are the hotspot functions.
