Jian He commented on YARN-7198:
-------------------------------
bq. 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.
Agree it's a bit overloaded, but unfortunately didn't come up with a better
name..
bq. 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?
yeah.. the "hadoop.registry.dns.bind-address" is missing, it was part of the
yarn-registry effort and so documented in the yarn registry service. I'll also
add it here.
bq. hadoop.registry.dns.zone-subnet
it's not CIDR notation, sample config is like below. But I think a CIDR
notation is even simpler. I've updated the sample configs in
ServiceDiscovery.md with the changes.
{code}
<property>
<name>hadoop.registry.dns.zone-mask</name>
<value>255.255.255.0</value>
</property>
<property>
<name>hadoop.registry.dns.zone-subnet</name>
<value>172.21.195.0</value>
</property>
