They're not going to be part of those stacks for much longer. As Ambari moves toward management packs in 3.0, they'll be their own stack essentially.
To your question - services can provide their own upgrade packs. Since these services are not part of the actual HDP stack, they should not be a part of the HDP pre-defined orchestration. Additionally, they are not "version-able", so Ambari wouldn't know to schedule them. If they provide their own upgrade pack, they can certainly be restarted as part of an HDP orchestration. > On Feb 17, 2017, at 11:21 AM, Di Li <[email protected]> wrote: > > Hello fellow Ambari developers, > > I noticed no RU/EU upgrade XML files include AMS or LogSearch.
