Hello,
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.
I have tried to recompile the java source code with the -g flag and updated the jar file however I still can not see what is inside the unknown module.
Can you please tell me what is the best way to solve this issue?
System information: Intel Atom with Linux OS
