@echarles For now, Zeppelin supports `per note` option but doesn't do `per
user`. If two different users log in Zeppelin and want to use same spark
interpreter with same note, they cannot run a paragraph simultaneously. This PR
enable that feature. Concerning ZEPPELIN-1000, I don't know the meaning of the
management of single user exactly. AFAIK, Zeppelin manages multiple users at
the same time. Could you please describe in details? I think you'd better
answer the moon's statement.
