I'm able to connect to the Cassandra cluster and can easily move data in and out of it, so that's great.\r\n\r\nHowever, one of the things that most excited me about the DSE is the integration with Spark. I'm new to DSE in general, so I apologize if this is a stupid question, but I cannot figure out how to turn Spark on in this cluster. The documentation says that nodes with Spark will have a star icon next to it, but nothing (I could find) about how to install Spark onto those nodes. It says that Spark is the default for analytics nodes, but I can't find anything on how to convert a node into an analytics node. Any help on this would be greatly appreciated. \r\n\r\nThank you in advance,\r\n-Alessandro Gagliardi"},"comment":{"url":"https://api.github.com/repos/DSPN/amazon-cloudformation-dse/issues/comments/267690899","html_url":"https://github.com/DSPN/amazon-cloudformation-dse/issues/26#issuecomment-267690899","issue_url":"https://api.github.com/repos/DSPN/amazon-cloudformation-dse/issues/26","id":267690899,"user":{"login":"cpoczatek","id":14008252,"avatar_url":"https://avatars.githubusercontent.com/u/14008252?v=3","gravatar_id":"","url":"https://api.github.com/users/cpoczatek","html_url":"https://github.com/cpoczatek","followers_url":"https://api.github.com/users/cpoczatek/followers","following_url":"https://api.github.com/users/cpoczatek/following{/other_user}","gists_url":"https://api.github.com/users/cpoczatek/gists{/gist_id}","starred_url":"https://api.github.com/users/cpoczatek/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/cpoczatek/subscriptions","organizations_url":"https://api.github.com/users/cpoczatek/orgs","repos_url":"https://api.github.com/users/cpoczatek/repos","events_url":"https://api.github.com/users/cpoczatek/events{/privacy}","received_events_url":"https://api.github.com/users/cpoczatek/received_events","type":"User","site_admin":false},"created_at":"2016-12-16T20:40:51Z","updated_at":"2016-12-16T20:40:51Z","body":"@MadDataScience I pushed the changes to the master branch. If you feel like using them look in [amazon-cloudformation-dse/multidc](https://github.com/DSPN/amazon-cloudformation-dse/tree/master/multidc). Ignore the *multidc* part, you can deploy just one datacenter. These scripts and templates leverage OpsCenter's [Lifecycle Manager](https://docs.datastax.com/en/opscenter/6.0/opsc/LCM/opscLCM.html) for the deployment. This get's you a few things:\r\n\r\n- Spark on by default. I set the default config here to have Spark/Solr/Graph on by default. (mixed workloads not recommended for production yada yada yada)\r\n\r\n- 99% of DSE's config is exposed in the LCM gui.\r\n\r\n- Maybe it makes sense for teaching to give each student a datacenter (with appropriate local replication factors). LCM does support multiple clusters (which would make more sense) but that's not going to work right now.\r\n\r\nThere's definitely bugs, and the doc could probably be clearer, but if you use it let me know and I'll try to fix stuff.\r\n"}}
