[jira] [Created] (HELIX-817) Support for multiple instance group tags for Job config

Dimuthu Upeksha created HELIX-817:
-------------------------------------

             Summary: Support for multiple instance group tags for Job config
                 Key: HELIX-817
                 URL: https://issues.apache.org/jira/browse/HELIX-817
             Project: Apache Helix
          Issue Type: New Feature
          Components: helix-core
    Affects Versions: 0.8.x
            Reporter: Dimuthu Upeksha


Currently we can set only one instance group tag for a job. 
 
jobCfg.setInstanceGroupTag("INSTANCEGROUPTAG");
 
It will be really helpful to support support multiple instance group tags for one job so that the job can be run either in group A or group B. Through this, we can support more advanced scheduling use cases like in Node Affinity in Kubernetes [1]
