Subject [jira] [Commented] (YARN-8900) [Router] Federation: routing getContainers REST invocations transparently to multiple RMs
Date Thu, 18 Oct 2018 10:46:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-8900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16655035#comment-16655035

Bibin A Chundatt commented on YARN-8900:

Thank you [~giovanni.fumarola] for patch.

Few comments

# Can we have a generic methods similar to FederationClientInterceptor#invokeConcurrent ?
getClusterMetricsInfo and getContainers and others can reuse.
# IMHO better to send exception, than empty response when clusters are not available. Applications
zero containers and  zero subcluster currently return empty.
