Allen Wittenauer edited comment on YARN-7198 at 10/4/17 3:41 AM: ----------------------------------------------------------------- I tried to run this based upon the documentation here: https://github.com/apache/hadoop/blob/63d1084e9781e0fee876916190b69f6242dd00e4/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-site/src/site/markdown/yarn-service/RegistryDNS.md Playing with this tonight, one thing has become really obvious: I'm looking in a directory called 'yarn-service' at documentation. If this is the 'yarn-service', then what is the rest of YARN? service is really not a good word to use. In fact, service is so over used in the YARN documentation (here and elsewhere) as a whole that it's lost all meaning. :( Anyway.... I tried to run this with these configs: {code} <property> <name>hadoop.registry.dns.enabled</name> <value>true</value> </property> <property> <name>hadoop.registry.dns.domain-name</name> <value>hadoop.example.com</value> </property> <property> <name>hadoop.registry.dns.bind-port</name> <value>54</value> </property> <property> <name>hadoop.registry.dns.zone-subnet</name> <value>172.16.170.0</value> </property> <property> <name>hadoop.registry.dns.zone-subnet</name> <value>255.255.255.0</value> </property> {code} It's interesting that it failed to start because it couldn't connect to ZK on localhost/127.0.0.1:2181. So I'm guessing there is a chunk of documentation missing? That said: bq. hadoop.registry.dns.zone-subnet How is this specified? CIDR notation? bq. hadoop.registry.dns.zone-mask OK, maybe not? An example really needs to exist in the markdown docs for these two entries about what is actually wanted here. For example, if I want 192.168.100.0/22 (aka 192.168.100.0 to 192.168.103.255), what does the configuration look like? If it supports CIDR, then zone-mask is pointless. But I'm guessing it only supports the classic class A, B, and C? This is really important because reverse addressing for non-standard network blocks is a bit wacky to configure even on standard DNS servers.
