I have a Jenkins pipeline job called "TestPipeline". I want to trigger a build on 2 different slaves which labeled "tester1' and "tester2". And the pipeline script is quite simple here:

node('tester1') {
    build 'test_job'
}
node('tester2') {
    build 'test_job'
}

However when I run the TestPipeline job, the "test_job" won't run on the nodes which I assigned. But run on random nodes instead.

I'm wondering if I should set "Restrict where this project can be run" on my "test_job". So I set it to "tester" (The "tester" label contains both node "tester1" and "tester2"). But when I run the pipeline job again, the "test_job" runs on "tester2" twice. I should expect the job to run on "tester1" first and then run on "tester2".

So the build job step runs regardless of node step?
