@Anpan K Yes , Atlas stores information in HBase. For fast information retrieval , the data need to be indexed and retrieved when queried. Atlas uses Janus Graph. Janus graph has 2 types of indexes : composite and mixed indexes. Composite indexes are supported with primary storage backend (HBase in this case), mixed graph indexes require indexing backend for full text search , numeric range search etc., Here , Solr is used by Atlas as indexing backend. You may read about Janus Graph for more detailed information.

@Anpan K Usually upon a saved change/new service install ambari will ask you to restart one or more services. . Ambari is aware that certain actions performed on service Y will require a restart of service X - Hence marks as restart is required. . Why restart is required sometimes requires you to know what have been latest changes performed. Check the services version and see if any changes have been done recently. Or perhaps a new service was added. HTH

@Anpan K Ambari Server uses Version Definition Files (VDF) to understand which product and component versions are included in a release. The VDF file contains various Operating System and their Repo URLs. VDFs also provides individual components name & version information that are shipped with that verison of product. Example: HDP 2.6.2 (VDF): http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.6.5.0/HDP-2.6.5.0-292.xml Users can also create their own VDFs (by following the same format as mentioned in the above VDF) by editing the <repoid/> tags informations for each repository to match their Local repository OR Satellite/Spacewalk channel names previously configured. VDFs helps in minimizing efforts in registering a new version. It also helps in automated cluster creation specially in case of Blueprints: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.0.0/bk_ambari-release-notes/content/ambari_relnotes-2.6.0.0-behavioral-changes.html
