Add aliases for short role names like nn, jt, tt, dn, zk
---------------------------------------------------------
Key: WHIRR-199
URL: https://issues.apache.org/jira/browse/WHIRR-199
Project: Whirr
Issue Type: Improvement
Components: service/hadoop, service/zookeeper
Reporter: Andrei Savu
Priority: Minor
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."
