----------------------------------------------
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.
