Gowtham,
Apache Atlas 2.1.0 uses JanusGraph 0.5.1, and JanusGraph removed support for embedded Cassandra since 0.5.0 – as can be seen in the following in Atlas server log: [main:] ~ Cassandra embedded solution is deprecated and will be removed with JanusGraph 0.5.0. For testing, please use JanusGraph Docker images: https://github.com/JanusGraph/janusgraph-docker. For production, please use a side-by-side deployment of Cassandra or a pre-packaged version of Cassandra with a CQL backend in JanusGraph 0.5.0. For more details, see https://docs.janusgraph.org/basics/server/. (CassandraEmbeddedStoreManager:81) Consider using alternate backend store – like HBase, or external Cassandra (i.e. not embedded). Hope this helps.

After all the setup have been done, we ran the atlas-start.py and the atlas is running on port 21000.When we are accessing the atlas, we are facing 503 Service Unavailable Error. We checked the logs from application.log file. We got below issue 2020-10-13 06:29:02,309 WARN - [main:] ~ JMX is not enabled to receive remote connections. Please see cassandra-env.sh for more info. (CassandraDaemon:81) 2020-10-13 06:29:02,310 ERROR - [main:] ~ cassandra.jmx.local.port missing from cassandra-env.sh, unable to start local JMX service.null (CassandraDaemon:87) We see there is no “cassandra-env.sh” file in atlas and we tried other ways and didn’t find any solution for the above error. Could you please help us in rectify these problem so that it will be very helpful to us. Thanks, Gowtham V
