> Project: Hadoop YARN
> Issue Type: Bug
> Components: applications, resourcemanager

> When RM failsover, it does _not_ auto re-register running apps and so they
> need to re-register when reconnecting to new primary. This is done by
> catching {{ApplicationMasterNotRegisteredException}} in *allocate* calls and
> re-registering. But *RequestHedgingRMFailoverProxyProvider* does _not_
> propagate {{YarnException}} as the actual invocation is done asynchronously
> using seperate threads, so AMs cannot reconnect to RM after failover.
> This JIRA proposes that the *RequestHedgingRMFailoverProxyProvider* propagate
> any {{YarnException}} that it encounters.
