             Summary: Add container tags to resource requests
                 Key: YARN-6345
                 URL: https://issues.apache.org/jira/browse/YARN-6345
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
            Reporter: Konstantinos Karanasos


This JIRA introduces the notion of container tags.
When an application submits container requests, it is allowed to attach to them a set of string tags. The corresponding resource requests will also carry these tags.
For example, a container that will be used for running an HBase Master can be marked with the tag "hb-m". Another one belonging to a ZooKeeper application, can be marked as "zk".
Through container tags, we will be able to express constraints that refer to containers with the given tags.
