------------------------------------
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has outdated info about a _SubCluster_.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.
