How to find execution time of a MapReduce job?
Hi,
Date date; long start, end; // for recording start and end time of job
date = new Date(); start = date.getTime(); // starting timer
job.waitForCompletion(true)
date = new Date(); end = date.getTime(); //end timer
log.info("Total Time (in milliseconds) = "+ (end-start));
log.info("Total Time (in seconds) = "+ (end-start)*0.001F);
I am not sure above is the correct way to find. Is there any other method
or API to find the execution time of a MapReduce job?
Thanks,

Hi,
You can get it from yarn api. You have to find out difference beteen
accpted and finish state of Job.
