[jira] [Updated] (YARN-7652) Handle AM register requests
asynchronously in FederationInterceptor
[ https://issues.apache.org/jira/browse/YARN-7652?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Subru Krishnan updated YARN-7652:
---------------------------------
Description: We (cc [~goiri]/[~botong]) observed that the {{FederationInterceptor}} in {{AMRMProxy}} (and consequently the AM) is blocked if the _StateStore_ has outdated info about a _SubCluster_.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. (was: 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that the {{FederationInterceptor}} in {{AMRMProxy}} and consequently the application is blocked if the _StateStore_ has outdated info about a _SubCluster_.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.)
