[jira] [Comment Edited] (YARN-3662) Federation Membership State
APIs
[ https://issues.apache.org/jira/browse/YARN-3662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15383428#comment-15383428 ]

---------------------------------------------------------------
Thanks [~leftnoteasy] for reviewing the APIs. I am attaching an updated patch (v3) that addresses your concerns on membership API, specifically:
* Renaming {{FederationMembershipState --> FederationMembershipStateStore}} as this is the equivalent of {{RMStateStore}} for Federation.
* Added an explicit {{FederationSubClusterHeartbeatRequest}}
* Renamed all the _address_ fields in {{FederationSubClusterInfo}} to _serviceAddress_
I'll also update YARN-5307 by renaming {{FederationApplicationState --> FederationApplicationStateStore}}.
Regarding your question about the Policy API, Carlo has uploaded the initial version of the Policies in YARN-5323 with a [summary|https://issues.apache.org/jira/browse/YARN-5323?focusedCommentId=15380907] of how they will be used in Federation. We are updating the API Javadoc in YARN-3664 to increase clarity.

> The Federation Application State encapsulates the information about the active RM of each sub-cluster that is participating in Federation. The information includes addresses for ClientRM, ApplicationMaster and Admin services along with the sub_cluster _capability_ which is currently defined by *ClusterMetricsInfo*. Please refer to the design doc in parent JIRA for further details.
