Pipeline "when" condition is evaluated on the node

Issue Type:	Bug
Assignee:	Dominik Bartholdi
Components:	conditional-buildstep-plugin, pipeline
Created:	2019-05-23 14:19
Environment:	Jenkins ver. 2.164.3
Priority:	Minor
Reporter:	Oren Shpigel

For the following code:

 
                                                                pipeline {
  agent any
  stages {
    stage('Test') {
      agent { label 'nodes' }
      steps {
        sh ''' # code to run tests '''
      }
    }
    stage('Deploy') {
      when {
        branch 'master'
      }
      agent { label 'specific-node' }
      steps {
        sh ''' # code to deploy '''
      }
    }
  }
 
                                                            

The "when" condition is being evaluated on 'specific-node' and causes a bottleneck, instead of being evaluated on the master, or on the node that ran the previous stage.
