Github user zjffdu commented on the issue: https://github.com/apache/zeppelin/pull/2434 @karuppayya Thanks for this PR. It is really helpful. Besides this, with more and more features added we have more and more duplicated code in `PySparkInterpreter`, `SparkInterpreter`, `SparkSQLInterpreter` and `SparkRInterpreter`. It is better to have a base class to handle all these common things. Anyway, we could do this in another PR. But I just feel we need to to asap. Because zeppelin code base become too large than it could be.
