> Whirr support the following instance roles: dn, jt, nn, tt, zk,
> hbase-avroserver, hbase-master, hbase-regionserver, hbase-restserver,
> hbase-thriftserver and as you can see the naming is inconsistent and
> sometimes it's hard to guess the meaning.
> Tom White replied on the email list:
> "The shorter names (nn, zk, etc) predate Whirr to when the roles were a part
> of the group name and had to be kept short to conform to various
> length restrictions. We do things differently now that we have multi-cloud
> support, so keeping them short is less important, and indeed with a global
> namespace (since service name is optional) there is even more reason to make
> them distinctive and unique. So I would suggest the longer, hyphenated form
> that we adopted for HBase, like hbase-regionserver; so the pattern is
> <service-name>-<daemon>.
> There's not much harm in keeping the shorter forms around, but we could
> introduce aliases like hadoop-namenode, zookeeper, etc and
> deprecate the short ones."
