> Key: YARN-8349
> URL: https://issues.apache.org/jira/browse/YARN-8349
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: yarn-native-services
> Affects Versions: 3.2.0, 3.1.1
> Reporter: Shane Kumpf
> Assignee: Billie Rinaldi
> Priority: Major
> Attachments: YARN-8349.1.patch, YARN-8349.2.patch, YARN-8349.3.patch,

>
> As the title states, when a service is killed by the RM (for exceeding its
> lifetime for example), the YARN registry entries should be cleaned up.
> Without cleanup, DNS can contain multiple hostnames for a single IP address
> in the case where IPs are reused. This impacts reverse lookups, which breaks
> services, such as kerberos, that depend on those lookups.
