@snowch Thanks for explanation. Make sense.
CI is failing with
[INFO] --- maven-checkstyle-plugin:2.13:check (checkstyle-fail-build) @
unexpected token: executor
[INFO] There are 1 checkstyle errors.
[ERROR] ZeppelinR.java[149:5] (extension) TreeWalker: Got an exception -
expecting EOF, found 'outputStream'
Could you take a look and make CI green?
