Github user felixcheung commented on the issue: https://github.com/apache/zeppelin/pull/1587 I think I can review this in more details, but is there a need to run both Python2 and Python 3 at the same time in the same environment? Most likely people will have chosen one? If one at a time is ok why not do this with an environment variable LIVY_PYTHON - this is the similar approach Spark has chosen - and must also apply here since Livy just kick off PySpark anyway. So there really only one can be set at a time. Or am I missing something?
