I think I found the root cause of the problem. The key issue is that
currently the build configuration packages
"zeppelin-zrinterpreter-0.6.0-SNAPSHOT.jar" under "interpreter/spark" instead
of under "interpreter/r" (as similar to other interpreter like "flink" or
"sh"). Then, when the registration process is done at "InterpreterFactory.java"
method "registerInterpreterFromResource" takes the "interpreter-setting.json"
from "zeppelin-spark-0.6.0-SNAPSHOT.jar". I will try change this configuration
and see whether it addressed the issue.
