Eric Yang updated YARN-8333: ---------------------------- Attachment: YARN-8333.003.patch > Load balance YARN services using RegistryDNS multiple A records > --------------------------------------------------------------- > > Key: YARN-8333 > URL: https://issues.apache.org/jira/browse/YARN-8333 > Project: Hadoop YARN > Issue Type: Improvement > Components: yarn-native-services > Affects Versions: 3.1.0 > Reporter: Eric Yang > Assignee: Eric Yang > Priority: Major > Attachments: YARN-8333.001.patch, YARN-8333.002.patch, > YARN-8333.003.patch > > > For scaling stateless containers, it would be great to support DNS round > robin for fault tolerance and load balancing. The current DNS record format > for RegistryDNS is > [container-instance].[application-name].[username].[domain]. For example: > {code} > appcatalog-0.appname.hbase.ycluster. IN A 123.123.123.120 > appcatalog-1.appname.hbase.ycluster. IN A 123.123.123.121 > appcatalog-2.appname.hbase.ycluster. IN A 123.123.123.122 > appcatalog-3.appname.hbase.ycluster. IN A 123.123.123.123 > {code} > It would be nice to add multi-A record that contains all IP addresses of the > same component in addition to the instance based records. For example: > {code} > appcatalog.appname.hbase.ycluster. IN A 123.123.123.120 > appcatalog.appname.hbase.ycluster. IN A 123.123.123.121 > appcatalog.appname.hbase.ycluster. IN A 123.123.123.122 > appcatalog.appname.hbase.ycluster. IN A 123.123.123.123 > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
