How to filter only the application ID from Yarn

Question

We need to filter only the application ID on notebookApp application:

yarn application -list | grep notebookapp | awk '{print 1ドル}' | grep -v INFO
25/04/24 08:30:31 INFO client.AHSProxy: Connecting to Application History server at pluto01/53.23.21.2:10200
25/04/24 08:30:31 INFO client.ConfiguredRMFailoverProxyProvider: Failing over to rm2
application_1745386419514_0015

While expected results:

application_1745386419514_0015

The ugly way is to redirect the output to file

yarn application -list | grep notebookapp | awk '{print 1ドル}' >/tmp/app_id.txt

and then capture the application ID from the file:

APP_ID=$(cat /tmp/app_id.txt)

but we do not want to redirect the results to file.

• 3aska: any chance you tried something like this? APP_ID=$(yarn application -list | grep notebookapp | awk '{print 1ドル}' | grep -v INFO)
