@zjffdu I've missed remove some scripts in `testing`. I'll fix it.
Concerning the modes, in an early stage of Spark, there're some different
behaviours of different modes, thus we need to test Zeppelin with Spark in a
standalone cluster, but for now, Spark become stable and if different modes
have different behaviours, it's definitely Spark's problem and Spark should fix
it. Thus I don't think we need to test Zeppelin a cluster mode. Furthermore,
personally, I don't know what benefit we have in a different test environment
between local and CI. In case of Python, I've experienced that some tests only
failed in CI, not in a local with different setting between them. I think we
should try to keep both environments equally.
