Subject [jira] [Created] (YARN-7652) Handle AM register requests asynchronously in FederationInterceptor
Date Wed, 13 Dec 2017 20:09:02 GMT
Subru Krishnan created YARN-7652:
------------------------------------

             Summary: Handle AM register requests asynchronously in FederationInterceptor
                 Key: YARN-7652
                 URL: https://issues.apache.org/jira/browse/YARN-7652
             Project: Hadoop YARN
          Issue Type: Bug
          Components: amrmproxy, federation
    Affects Versions: 2.9.0, 3.0.0
            Reporter: Subru Krishnan
            Assignee: Botong Huang


We (cc [~goiri]/[~botong]) observed that the {{FederationInterceptor}} in {{AMRMProxy}} and
consequently the application is blocked if the _StateStore_ has outdated info about a _SubCluster_.
This is because we handle AM register requests synchronously. This jira proposes to move to
async similar to how we operate with allocate invocations.
