Billie Rinaldi commented on HADOOP-15821:
-----------------------------------------
Hi [~elgoiri], thanks for working on this patch! It's looking good so far.
Another area we'll have to address is the RegistryDNS daemon command in
hadoop-yarn-project/hadoop-yarn/bin/yarn as well as the exports
YARN_REGISTRYDNS_SECURE_USER, YARN_REGISTRYDNS_SECURE_EXTRA_OPTS in
hadoop-yarn-project/hadoop-yarn/conf/yarn-env.sh. This might be a candidate for
backwards compatibility. Maybe we could keep the yarn command and env vars for
starting the daemon as deprecated, while also introducing a hadoop command? I'm
open to suggestions.
There is also some documentation about how to configure and start RegistryDNS
here:
hadoop-yarn-project/hadoop-yarn/hadoop-yarn-site/src/site/markdown/yarn-service/ServiceDiscovery.md
hadoop-yarn-project/hadoop-yarn/hadoop-yarn-site/src/site/markdown/yarn-service/RegistryDNS.md
I'll try to test out the patch and see if I can find anything else.

> Currently, Hadoop YARN Registry is in YARN. However, this can be used by
> other parts of the project (e.g., HDFS). In addition, it does not have any
> real dependency to YARN.
> We should move it into commons and make it Hadoop Registry.
