Atlas web UI alert after performing stack upgrade to HDP 2.5 and adding Atlas 
Service


Bugs: AMBARI-18368
    https://issues.apache.org/jira/browse/AMBARI-18368


Repository: ambari


Description
-------

Steps to Reproduce:

* Install Ambari 2.2.2 with HDP 2.4 with HBase, Solr, and Hive (this is 
important)
* Perform EU/RU to HDP 2.5 
* Add Atlas Service

Atlas Server log contains,

Caused by: 
org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error 
from server at 
http://natu146-ehbs-dgm10toeriesec-u14-1.openstacklocal:8886/solr: Can not find 
the specified config set: vertex_index  

Fix:
The Hive RPM installs /usr/$stack/$version/atlas with some partial packages 
that contain Hive hooks, while the Atlas RPM is responsible for installing the 
full content.
If the user does not have Atlas currently installed on their stack, then 
/usr/$stack/current/atlas-client will be a broken symlink, and we should not 
create the symlink /etc/atlas/conf -> /usr/$stack/current/atlas-client/conf .
If we mistakenly create this symlink, then when the user performs an EU/RU and 
then adds Atlas service then the Atlas RPM will not be able to copy its 
artifacts into /etc/atlas/conf directory and therefore prevent Ambari from by 
copying those unmanaged contents into /etc/atlas/$version/0

Further, when installing Atlas service, we must copy the artifacts from 
/etc/atlas/conf.backup/* to /etc/atlas/conf (which is now a symlink to 
/usr/hdp/current/atlas-client/conf/) with the no-clobber flag.
