• How to access the metadata.

• Metadata store: Metadata is modeled using a graph model, implemented using the Graph database Titan. Titan has options for a variety of backing stores for persisting the graph, including an embedded Berkeley DB, Apache HBase and Apache Cassandra. The choice of the backing store determines the level of service availability.

* Hbase as the Storage Backend for the Graph Repository

By default, Atlas uses Titan as the graph repository and is the only graph repository implementation available currently. The HBase versions currently supported are 1.1.x. For configuring ATLAS graph persistence on HBase, please go through the "Configuration - Graph persistence engine - HBase" section for more details.

* Configuring SOLR as the Indexing Backend for the Graph Repository

By default, Atlas uses Titan as the graph repository and is the only graph repository implementation available currently. For configuring Titan to work with Solr, please follow the instructions below

The data is in /var/lib/atlas/data

[root@sandbox atlas]# pwd
/var/lib/atlas
[root@sandbox atlas]# ls
data  server
[root@sandbox atlas]# cd data/
[root@sandbox data]# ls
berkeley  es

Atlas uses Titan DB, which stores the data on local disk *.jdb

[root@sandbox berkeley]# ls -ltra

There are a few tools available to view titan db file - See below link
