Work Description: smolnar82 opened a new pull request, #636:
URL: https://github.com/apache/knox/pull/636
## What changes were proposed in this pull request?
Knox's automated service discovery had a bug when it came to HIVE(_ON_TEZ)
service discovery. These services have their SSL-enabled flag on the service
level, but the generated service model (by Knox) stored that information in the
HS2 role configs.
In addition to this, the CM configuration name referred to the so-called
`related name` configuration field which Knox does not consider when comparing
previous and current service/role configs.
## How was this patch tested?
Updated JUnit tests and executed manual testing in a cluster with KNOX, HIVE
and HIVE_ON_TEZ.
