Kill yarn application by Application-Name

Question

I want to create a cron to kill a yarn application (Spark) by it application name. But i found thant yarn application -kill needs an application ID. Is there a solution to kill it by application name, or to get the application ID using the application name.

Thank you

The output of the 'yarn application -list' contains the following information of yarn applications:

• Application-Id
• Application-Name
• Application-Type
• User
• Queue
• State
• Final-State
• Progress
• Tracking-URL

You can list the applications and awk by the required parameter. For ex: to list the applications by 'Application-Name'

yarn application -list | awk '$2 == "APPLICATION_NAME" { print $1 }' > applications_list.txt

Then you can iterate through the file and kill the applications as below:

while read p; do echo $p yarn application -kill $p done <applications_list.txt
