Hello Group! I'm trying to leverage various R functions in Zeppelin but am having challenges in figuring out how to configure the Spark interpreter/ SPARK_HOME variable.
I'm going by this <https://zeppelin.apache.org/docs/0.6.0/interpreter/r.html> documentation for now, and specifically have issues with the following steps: 1. To run R code and visualize plots in Apache Zeppelin, you will need R on your master node (or your dev laptop). For Centos: yum install R R-devel libcurl-devel openssl-devel For Ubuntu: apt-get install r-base How do I figure out the master node and install the R interpreter? Novice user here. 2. To run Zeppelin with the R Interpreter, the SPARK_HOME environment variable must be set. The best way to do this is by editing conf/zeppelin-env.sh. If it is not set, the R Interpreter will not be able to interface with Spark. You should also copy conf/zeppelin-site.xml.template to conf/zeppelin-site.xml. That will ensure that Zeppelin sees the R Interpreter the first time it starts up. No idea as to how to do step 2 either. Appreciate your help. If there is a video that you can point me to that talks about these steps, that would be fantabulous. Thanks! Shan -- Shan S. Potti,
