@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 â 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
