---------------------------------
Summary: Remove YARN registry entries when a service is killed by
the RM
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
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.
