[jira] [Comment Edited] (YARN-5531) UnmanagedAM pool manager for
federating application across clusters
[ https://issues.apache.org/jira/browse/YARN-5531?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15957131#comment-15957131 ]

Thanks [~kasha] for the review! For 2, sure I will add more logs. For 1, to me this class is more like a library rather than a service, which hides the fact that this is an UAM in the remote Yarn cluster, and present an aync version of {{ApplicationMasterProtocol}} interface to user (the actual AM). We can modify it into a service as well if needed.
[~subru]: along this line of thought, maybe we should call this class UnmanagedApplicationMasterProxy? Thanks!

> 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.
