Thanks!

I am not an R expert, but I found that much of the ggplot visualization is broken, because it expects it to be rendered locally. If you run in a yarn-client mode, as we are, ggplot doesn't work.

Correct, that page clearly says the R interpreter is supported 🙂 That doesn't seem to be the case.

Thanks Laurence, that explains a lot. R was already on the cluster, and I had to manually configure and start Livy, and then it worked. I expected Ambari to start Livy on the same host that Zeppelin was installed on, but that didn't happen. This post was very helpful in starting the server. https://community.hortonworks.com/articles/34424/apache-zeppelin-on-hdp-242.html Once livy was up and running I was able to run sparkR commands.

This was very helpful, but Livy did not pick up /etc/livy/conf/livy-defaults.conf! I changed the name to /etc/livy/conf/livy.conf and impersonation worked.

Version Information: CentOS release 6.7 (Final) Ambari 2.4.0.1 HDP 2.5.0.0 Zeppelin 0.6.0.2.5.0.0-1245 R version 3.2.3 is installed on all data nodes. I followed the below directions to install Zeppelin on data node 01. https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_zeppelin-component-guide/content/ch_overview.html When I view the interpreters tab, the following interpreters appear. - angular - jdbc - livy - markdown - sh - spark By using the example notebooks, I can see that the %sh, %md, and %pyspark interpreters work, but no %r interpreter exists. No %r interpreter. No %sparkr interpreter. Does the ambari deployed Zeppelin not support R? This says it does. https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_zeppelin-component-guide/content/using-interp.html Or is there some hook that only invokes it if it detects a certain version ?
