----------------------------------------------

             Summary: yarn.am.container.label is applied to entire samza job (all its containers) instead of only the AM.
                 Key: SAMZA-2619
                 URL: https://issues.apache.org/jira/browse/SAMZA-2619
             Project: Samza
          Issue Type: Bug
            Reporter: Lakshmi Manasa Gaduputi
            Assignee: Lakshmi Manasa Gaduputi


yarn.am.container.label is applied to entire samza job (all its containers) instead of only the AM.

Yarn supports 3 forms of applying node label to containers – am only, container only and entire job. [https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/NodeLabel.html#Specifying_node_label_for_application

]Samza's ClientHelper.scala finds the am container label and applies it to the application submission context which applies the label to the entire job instead of only the am. 

this restricts jobs which prefer to have label only for am or different labels for am and containers.
