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