Subject [jira] [Commented] (YARN-7592) yarn.federation.failover.enabled missing in yarn-default.xml
Date Tue, 09 Oct 2018 18:58:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7592?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16643949#comment-16643949

Subru Krishnan commented on YARN-7592:

I want to make sure I fully understand the proposal - we will revert the changes in {{{{RMProxy}}}}
and create the {{{{FederationClientRMProxy}} (I feel we can skip custom) directly if *yarn.federation.enabled*
is set? }}

I like the idea, can you ensure couple of things:
 * This works with both HA enabled or not (for NM, router and AMRMProxy).
 * Assuming above is true, can we remove *yarn.federation.failover.enabled* flag completely?


Thanks for working on this!

> yarn.federation.failover.enabled should be documented in yarn-default.xml. I am also
not sure why it should be true by default and force the HA retry policy in {{RMProxy#createRMProxy}}
