-------------------------------
Summary: RegistryDNS hang when remote lookup does not reply
Key: YARN-8600
URL: https://issues.apache.org/jira/browse/YARN-8600
Project: Hadoop YARN
Issue Type: Bug
Components: yarn
Affects Versions: 3.1.0
Reporter: Eric Yang
If lookup type mismatch with the record to query, remote DNS server might not
reply. For example looking up a CNAME record with a PTR address:
1.76.27.172.in-addr.arpa. This can hang registryDNS.
