System.out.println in Hadoop Driver Class

2020-05-02T17:09:11

I want to measure time to Hadoop job to execute. In my Driver class I have:

long start = System.currentTimeMillis();
long end = System.currentTimeMillis();
System.out.println(end-start);

But where does hadoop send the System.out.println()?

EDIT

When the program ends the terminal prints out Job Counters, can I get the total execution time as:

Total execution time = Total time spent by all maps in occupied slots + Total time spent by all reduces in occupied slots + Total time spent by all maps task + Total time spent by all reduces task ?
