Hi @amestry , 

 

Thanks for sending the link. However, both Atlas 1.1.0 and Atlas 2.0 use JanusGraph database. 

 

Can you tell me on how to just upgrade the version, by using the latest download of Atlas 2.0?

 

Also, how to configure Cassandra as the DB for Atlas 2.0?  Please let me know your inputs. 

 

Thanks and Regards,

Hi

 

Sorry for the delay in replying to your message.

 

You are right, Atlas 1.0 onwards we are using JanusGraph.

 

Can you tell me on how to just upgrade the version, by using the latest download of Atlas 2.0?

I am not sure what you are looking for. It would be good if you can elaborate on this.

 

From our experience, upgrading JanusGraph version was as easy as updating the version in POM.xml and then running our test suite. There were few glitches we discovered in few versions. But it was something we could resolve quickly.

 

Also, how to configure Cassandra as the DB for Atlas 2.0?

I have not tried this personally. But my thinking is that the steps are similar to that of using HBase as backend. The configuration would be to ensure that JanusGraph gets the requisite properties for its initialization.

 

Please see here for details.

 

There was a community effort in the past to make Cassandra work with Atlas.

 

Hope this helps.

Hi @amestry , 

 

Thanks a lot for your inputs. 

 

I was able to upgrade the ATLAS Version by using the below steps:

Step 1:  Downloaded the latest version (using V2.0 as client and V3.0 as Dashboard) from Git Atlas Master branch 

Step 2:   Modified the atlas-application.properties, set the correct DEFAULT_ATLAS_SERVER_HOST in atlas_config.py, set the HBASE_CONF_DIR to the hbase conf directory in the local machine 

Step 3:   Executed the python script "atlas_start.py" to start the Atlas server at port 21000

 

Now, I am able to login to ATLAS website without any issues. 

 

Thanks and Regards,
