> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: yarn-native-services
> Affects Versions: 3.2.0, 3.1.1

> 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.
