Subject [YARN-6483] Add nodes transitioning to DECOMMISSIONING state to the list of updated nodes returned by the Resource Manager as a response to the Application Master heartbeat
Date Mon, 13 Nov 2017 01:27:09 GMT
Hi,

I have submitted a pull request https://github.com/apache/hadoop/pull/289
 for https://issues.apache.org/jira/browse/YARN-6483. This change is an
alternative proposal to YARN-3224, for notifying application masters about
the decommission of a node, that could help completing https://issues.
apache.org/jira/browse/YARN-914. This could be useful for implementing
functionality like for example https://github.com/apache/spark/pull/19267,
where a Spark AM is able to blacklist executors when their corresponding
node transitions into DECOMMISSIONING state.

I would like to hear your feedback on this.

Thanks,

Juan Rodriguez Hortala
