Installing Apache Atlas
Also available as:


In HDP-3.0+, Apache Atlas uses the JanusGraph graph database to store metadata objects. In earlier versions, Atlas used the Titan graph database for metadata storage. When upgrading to HDP-3.0 and higher versions, you must use a command-line migration tool to migrate the Atlas metadata from Titan to JanusGraph.

  1. Estimate the size of the existing Atlas repository and the time it will take to export the metadata from HDP 2.x Titan database to the HDP 3.x JanusGraph database.
  2. Use the Atlas metadata migration tool to export the Atlas metadata from HDP 2.x.
  3. Import the Atlas metadata into HDP 3.x.
