Subject [jira] [Commented] (YARN-5531) UnmanagedAM pool manager for federating application across clusters
Date Sat, 06 May 2017 00:56:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-5531?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15999197#comment-15999197

Botong Huang commented on YARN-5531:
------------------------------------

Thanks [~subru] for the review! I've fixed all except:
"this check is not correct as once we have HA (YARN-6128)". I will address this in YARN-6128
because we need to refactor the code there anyways. 

Good catch on "testForceKill", it turns out that the unit test is not written correctly and
it was actually catching the Assert.fail() one line above and pass the test!

> One of the main tenets the YARN Federation is to *transparently* scale applications across
multiple clusters. This is achieved by running UAMs on behalf of the application on other
clusters. This JIRA tracks the addition of a UnmanagedAM pool manager for federating application
across clusters which will be used the FederationInterceptor (YARN-3666) which is part of
the AMRMProxy pipeline introduced in YARN-2884.
