Ramesh Mani commented on RANGER-1201:
-------------------------------------
[~zhangqiang2] In HA mode RMs can be one or more and all are configured via
zookeeper.
https://hadoop.apache.org/docs/r2.4.1/hadoop-yarn/hadoop-yarn-site/ResourceManagerHA.html
So it would be a scalable solution if we can use RM Client APIs to find the
ACTIVE RM and do the Lookup / Test Connection in Ranger Yarn Plugin than
providing one additional config to store one more standby RM.
https://hadoop.apache.org/docs/r2.4.1/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html
If there are no API from finding all the RMs then we can have a config to hold
the list of RMs and then find which one is active and use it. What do you thing?
> Ranger admin support yarn HA, support standby yarn rest url configuration
> when creating yarn service.

> In ranger admin, when creating yarn service, there is yarn.rest.url for yarn
> active resourcemanger, if yarn is in HA mode, add yarn.rest.url.standby for
> yarn standby resourcemanger, so if yarn active RM is out of service, ranger
> admin can try yarn standby RM to
> support autocomplete for resource names when creating policies of yarn
> service.
