nice command is used for changing priority of the jobs.
Syntax: nice [OPTION] [COMMAND [ARG]...]
Range of priority goes from -20 (highest priority) to 19 (lowest).Priority is given to a job so that the most important job is executed first by the kernel and then the other least important jobs. This takes less CPU times as the jobs are scheduled and are given priorities so the CPU executes fast. The priority is given by numbers like -20 describe the highest priority and 19 describe the least priority.

How to find execution time of a MapReduce job?

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 this is the correct way to find. Is there any other method or API to find the execution time of a MapReduce job?

Add time to log file for cron job

I'm trying to figure out a way to insert a timestamp into a log file I'm creating for a cron job:

/usr/bin/rsync -v --min-size=1 -rlpgo -O --inplace /home/myuser/Get*
root@xx.x.xx.xx:/mnt/yyy/zzz/compass 2>&1 >& /tmp/rsync_user.log

I've googled this but all I could find are tips on how to add the time and date to the name of the log file itself, not to the contents of the log.

Any tips or pointers would be great.
