Falcon - Atlas backend store

[#1]

Hi,

What is the backend store for Falcon and Atlas, is it HBASE? is any other store possible?

Thanks,

HBase is the preferred metadata store for Atlas as of now. BerkeleyDB can also be used.

note that Atlas uses Titan (graphDB) as a metadata store, and this uses HBase for metadata and Solr for indexing

Hi @Greg Keys, so is HBASE and SOLR mandatory to be able to use Atlas?

Yes. (They are installed under the covers when installing Atlas service).
