Konstantinos Karanasos commented on YARN-6345: ---------------------------------------------- bq. Is there any value in using a key-value pair in your case with no value, so that we can reuse the feature in YARN-5986? This would simplify the container launch context protocol in the long run I think. In our case, I don't think there are use cases for which a value will be needed. How would it simplify the CLC though? > Add container tags to resource requests > --------------------------------------- > > Key: YARN-6345 > URL: https://issues.apache.org/jira/browse/YARN-6345 > Project: Hadoop YARN > Issue Type: Sub-task > Components: yarn > Reporter: Konstantinos Karanasos > Assignee: Panagiotis Garefalakis > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
