How Hadoop kill all jobs for a specified user

Today, some classmates asked me, how to kill the user to make all the job, there is no ready-made command? I looked at the prompt for the Hadoop job command, and there was no such command.
In fact, the implementation of the kill specified user's job is also very simple, the Hadoop job command itself has a lot of practical job management functions.

List all the jobs on the Jobtracer

hadoop job -list

Use Hadoop Job-kill to kill the specified Jobid

hadoop job -kill job_id

Combine the above two commands to kill the job for the specified user

for i in `hadoop job -list | grep -w username| awk ‘{print $1}‘ | grep job_`; do hadoop job -kill $i; done


将上面的username替换为运行任务的用户名字，否则kill不掉
