Hi @Krishna Srinivas
Atlas 0.8 has a data model for HBase which define several components (HBase_namespace, HBase_table, etc). However, there's no automated scrolling of HBase that scroll over all tables and save data in Atlas. You can write a script that do this and update ATlas through it event or REST API.
You have some examples here : https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.4/bk_data-governance/content/atlas_messaging_...
You can also manually create HBase entity through Atlas UI of you don't have lot of tables
