@Maryem Mary,

You can use the mapreduce command line tool to get the execution time for each job. Use the below command to get all the stats of a job

mapred job -status {job-id}

.

To get the execution time, use

mapred job -status {job_id} | grep "CPU time"

.

If you have YARN application Id ,then replace 'application_xxx' with 'job_xxx' to get the mapreduce job id.

.

If you have written the Mapreduce application, then you can have custom counters as well to print extra information. See the example in the link
