    @jongyoul sorry for late response!
    
    I checked failure. It's related to PR but I don't know how to fix it
    
    Build profile uses
    ```
    $ export SCALA_VER="2.11"
    $ export SPARK_VER="1.6.3"
    ```
    
    `downloadSpark.sh` downloads spark prebuilt for scala 2.10. So we have 
incompatible versions of scala.
    
    I tried to build spark 1.6 with scala 2.11 — R interpreter works fine. 
But spark does not provide such binary distribution.
    
    Does Zeppelin support spark 1.6 with scala 2.11? Then we should provide 
binary spark distribution for this build profile. I think it affects not only R 
interpreter
    
    This code 
https://github.com/apache/zeppelin/blob/master/zeppelin-server/src/test/java/org/apache/zeppelin/rest/AbstractTestRestApi.java#L152
 exclude R interpreter during tests. But it doesn't work with new registration
