> Key: YARN-3221
> URL: https://issues.apache.org/jira/browse/YARN-3221
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.6.0
> Reporter: Sidharta Seethana
> Priority: Major
>
> Today, it is not possible for YARN applications to 're-register' in failure/restart scenarios. This is especially problematic for Unmanaged applications - when restarts (normal or otherwise) or other failures necessitate the re-creation of the AMRMClient (along with a reset of the internal RPC counter). The YARN RM disallows an attempt to register again (with the same saved token) with the following exception shown below. This should be fixed.
