[zeppelin] branch branch-0.8 updated: [ZEPPELIN-4007]. Travis CI is broken for branch-0.8

This is an automated email from the ASF dual-hosted git repository.

zjffdu pushed a commit to branch branch-0.8
in repository https://gitbox.apache.org/repos/asf/zeppelin.git


The following commit(s) were added to refs/heads/branch-0.8 by this push:
     new 1cd8618  [ZEPPELIN-4007]. Travis CI is broken for branch-0.8
1cd8618 is described below

commit 1cd86182b42452476e2621094019305191a5ced2
Author: Jeff Zhang <zj...@apache.org>
AuthorDate: Thu Feb 14 13:27:12 2019 +0800

    [ZEPPELIN-4007]. Travis CI is broken for branch-0.8
    
    ### What is this PR for?
    
    This PR fix several issues on branch-0.8 to make the CI pass.
    
    1. netty of python's grpc dependencies is conflicted with that of spark. This PR upgrade the grpc version of python interpreter.
    2. change paragraph running via z.runNote from blocking to non-blocking. Otherwise the paragraph output is missing (ZeppelinSparkClusterTest#zRunTest will fail).
    3. Separate each spark version integration into separate classes. Just like what we did in #3306
    
    ### What type of PR is it?
    [Bug Fix | Refactoring]
    
    ### Todos
    * [ ] - Task
    
    ### What is the Jira issue?
    * https://jira.apache.org/jira/browse/ZEPPELIN-4007
    
    ### How should this be tested?
    * CI pass
    
    ### Screenshots (if appropriate)
    
    ### Questions:
    * Does the licenses files need update? No
    * Is there breaking changes for older versions? No
    * Does this needs documentation? No
    
    Author: Jeff Zhang <zj...@apache.org>
    
    Closes #3309 from zjffdu/ZEPPELIN-4007 and squashes the following commits:
